4.  Known Issues
================

4.1  Maximizing then restoring seamless windows can cause display corruption 
----------------------------------------------------------------------------
If you maximize a seamless window from the taskbar and then restore the window 
using the title bar, the display may appear corrupted. To avoid this issue, 
if you maximize a seamless window from the taskbar, ensure you restore the 
window from the taskbar rather than from the title bar. [#143377]

4.2  Some keys do not work in the simplified Chinese locale on some distributions 
---------------------------------------------------------------------------------
The arrow, Home, End, Page Up, and Page Down keys do not work in the simplified
Chinese locale on some Linux distributions. You can fix this problem by removing 
the following line from the client's module.ini file:
UseLocalM=True
[#150369]

4.3  Cursor disappears intermittently from the PNA Configuration dialog box 
---------------------------------------------------------------------------
When entering a server URL on the PNA Configuration dialog box, the cursor 
occasionally disappears. If you click the dropdown arrow and then reselect 
the text box, the cursor reappears.
[#140781]

4.4  The Firewall dialog box does not accept non-ASCII characters
-----------------------------------------------------------------
The Firewall dialog box does not accept non-ASCII characters. If 
you want to enable non-ASCII characters on this dialog box, 
either comment out or remove the following lines from the Wfica 
resource file in the client's installation directory:
Wfica*ProxyAuthDialog.ProxyUsername*international: False
Wfica*ProxyAuthDialog.ProxyPassword*international: False

Note that due to a third party issue, this workaround may cause 
the client to shut down unexpectedly on some Linux distributions 
if a user double-clicks on the dialog box.
[#150143]

4.5  The minimum size bitmap for caching cannot be set using the arrow keys
---------------------------------------------------------------------------
When setting the minimum size bitmap to be cached on the Disk Cache dialog 
box, you cannot scroll using the arrow keys. To avoid this issue, either 
use the mouse to set the value, or hold down CTRL while scrolling with the 
arrow keys. 
[#151053]

4.6  The Connection Status dialog box does not display the Euro character correctly
-----------------------------------------------------------------------------------
If you log on to a connection and your user name contains a Euro character, this 
character does not display correctly on the Connection Status dialog box in the 
Connection Center. There is no workaround for this issue.
[#151152]

4.7  The client may not start correctly when using en_GB.UTF-8 on SuSE 10.x
---------------------------------------------------------------------------
Using en_GB.UTF-8 on SuSE 10.x, the client may not start correctly when it 
uses the fallback font specification in the fontList. You can modify the 
Wfcmgr resource file in the $ICAROOT/nls/{language}/UTF-8 directory to 
fix this issue. Update the final two lines in the Wfcmgr*fontList section 
as follows:
-*-*-medium-r-*-*-*-120-75-75-c-*-*-*;\
-*-*-medium-r-*-*-*-120-*-*-c-*-*-*:
This specifies the use of character-cell (fixed cell size) fonts and so 
avoids using the fallback font specification.
[#151365]

4.8  PowerPoint files on mapped client drives may allow concurrent access
-------------------------------------------------------------------------
Version 10.x of the Clients for UNIX supports file locking on mapped client 
drives. This prevents concurrent write access to Microsoft Word documents, 
Microsoft Excel documents, and other files on mapped drives. However, 
some applications restrict multiple access by opening files using Windows 
sharing modes, which are not supported on UNIX platforms. As a result, 
concurrent write access to Microsoft PowerPoint files is permitted in some 
circumstances when it should not be possible. If you need concurrent access 
to PowerPoint files, Citrix recommends putting these files on a file system 
that is accessible from the server, rather than on a client mapped drive. 
[#151466]

5.  Fixes applied since last full release
=========================================

The last full releases were 10.0 (Linux: English, German and Japanese).

Build    Fix

1        Fixes a failure to disconnect the session if the smart card used for
         logon is removed during a reconnected session with a server running 
         Citrix Presentation Server version version 4.0. (Hotfix Rollup Pack 
         3 or later must be installed on the server.) Corrects problems 
         that prevent the client from running on Ubuntu Linux version 6.10.

         This build also includes all fixes from versions 9.43 to 9.49.

         9.43:
         Fixes a problem that prevented the Microsoft Windows "Snap To"
         mouse option from working.

         9.44:
         Ensures that the maximization state of seamless windows is correctly
         restored when they are maximized after being reduced to icon size. 
         Adds a "TWIConfineToWorkArea" configuration option that can be set 
         "Off" to allow seamless windows to be moved outside the work area. 
         Also adds configuration parameters "PointerGrabTime" and 
         "PointerClickTime" to set two timer parameters for pointer position 
         echo suppression. They control the period after a mouse position 
         report is sent during which any server-originated positions are 
         discarded as echoes, and the period after a mouse click during which 
         all server positions are accepted as a response to the click. Values 
         are in milliseconds.

         9.45: Citrix internal build.

         9.46:
         Corrects an error in the treatment of the "BrowserTimeout" parameter
         that was introduced in build 9.20. The SCardListReaders function
         can now be called with a null context parameter when using the
         smart card virtual channel. The pnabrowse utility now enumerates
         applications correctly when $HOME/.ICAClient has not been populated.

         9.47:
         Improves the change to pointer positioning introduced in version 9.43
         and prevents client work-area information from having an effect
         in non-seamless sessions. Corrects an error in the pnabrowse utility
         that stopped it working with some server configurations.

         9.48:
         Corrects the modification time of files edited using client drive
         mapping. Corrects an error in the pnabrowse utility that could stop it
         launching published applications.

         9.49:
         Corrects an error that may inhibit session sharing when one seamless
         session is started within a few seconds of another.  Adds special
         behaviour to the smart card virtual channel to correct problems with
         a particular application following session reconnection.  That is
         controlled by a new configuration parameter "UCSCWAMap", and is
         normally disabled.

2        Causes tear-off menus from Microsoft Windows applications to vanish
         correctly when the application loses focus. Improves the drawing
         performance with seamless windows, particularly in 256-color sessions
         with multiple windows. Adds workspace control operations to the
         pnabrowse utility.

3        Fixes incorrect use of SSL error message 47.

4        Enlarges the sensitive area of notification area icons, improves text
         parameter handling in locales using the ISO 8859-15 character set and
         improves reconnection to multiple sessions using pnabrowse.

5        Fixes a font problem when using Ubuntu Linux version 7, and
         the appearance of some application icons in non-seamless sessions.
         Corrects Program Neighborhood's handling of 8-bit characters in
         user and client names when using non-UTF8 locales.
         Corrects the behaviour of seamless sessions started by Web Interface
         or Program Neighborhood Agent, when the default session type is
         full screen.

6        Updated for release to Web.

7        Adds support for Philips SpeechMike Pro LFH5274 device, activated
         by the configuration option "USBSpeechMikeUsesDevHID=True".  Adds
         "/opt/Citrix/ICAClient" to the list of standard installation
         locations for compatability with Debian packages.

8        Adds configuration option TWIDropFocus.  When set, focus loss events
         are forwarded to the session host.

9        Corrects failure of a published application to respond to a mouse
         click following restoration of an associated Windows language bar.

10       Fixes problems with the "-clientfile" and "-protocolfile" command
         options of wfica.  Also fixes spurious key release events with
         Philips SpeechMike Pro LFH5274 devices.

11       Fixes problems iconifying windows from Windows Task Manager and
         Microsoft Outlook.  Also improves the change introduced in 10.9
         to cover the case of using two different mouse buttons.

12       Corrects an error in version 10.11 that caused some
         windows to have inappropriate task bar entries.

13       Fixes graphics corruption when moving a partially-obscured, 256-color
         Seamless window.  Corrects the treatment of Seamless windows that
         are iconized immediately after being created.  Improves the behaviour
         of Seamless windows with the TOPMOST attribute in GNOME and KDE
         environments.

14       Ensures that windows with minimize buttons also have their own
         task bar entries or window manager icons.  A new configuration
         option, ResizeSession, can be used to disable the dynamic resizing
         of non-Seamless session windows.

15       Enables locking of all serial ports accessed through the ICA serial
         port virtual channel.

16       Improves the mechanism for setting server focus in response to
         local window manager actions.

17       Improves the handling of keys that are pressed inside a session window
         and released outside, preventing the loss of parts of multiple item
         selections in scrolled windows.  Also fixes an infinite loop that
         may occur when processing the XAPPLRESDIR and XUSERFILESEARCHPATH
         environment variables.

18       Fixes a locking problem that prevents Microsoft Excel from opening
         client files.  Also adds a configuration option, TWIIgnoreNormalState,
         that can be set to workaround a window manager quirk that causes
         new windows that are created as icons to be restored prematurely.

19       Improves the change in build 10.13 for windows with the TOPMOST
         attribute to cover changes in the attribute following window creation.

20       Fixes a keyboard problem: if Alt-Tab is used to switch focus away
         from an ICA session window, it may behave as if the Alt key is pressed
         on the keystroke that follows the return of focus.

21       Corrects an error in marshalling ICA protocol data.

22       Prevents a rare client crash when using SSL; fixes a problem when
         raising maximized Seamless windows; corrects text layout in
         the "Window" properties dialog.

23       OEM release. Also fixes session sharing with Program Neighborhood
         Agent.

24       Allows audio to recover from a device error.

25       Modifies the effect of requesting a session that occupies 100% of the
         screen so that a maximized window is used; fixes a graphic corruption
         error in 256-color sessions; prevents a client crash when applications
         use large cursors; fixes a drawing error that can occur with
         SpeedScreen Latency Reduction.

26       Makes control of audio volume and playback rate configurable.

27       Fixes a locking problem that prevents some applications from
         accessing files;  modifies the handling of SJIS-encoded ICA files
         for compatability with existing Web Interface servers; improves the
         propagation of focus changes to Seamless windows to better handle
         modal dialogs; corrects the icons of some Seamless dialog windows;
         removes a now obsolete entry from KDE and GNOME system menus.

28       Fixes a problem with highlighting when using the mouse to select text 
         in Microsoft Word.

29       Fixes a problem with recognising PDAs; supports up to 5 mouse buttons.

30       Fixes failures of automatic reconnect caused by premature deletion
         of the ICA file.  Allows files to be mapped via symbolic links
         while maintaining link checking.

31       Fixes SSL failure when the server certificate is encoded in UTF-8.

32       OEM release.

33       Fixes a performance problem introduced in 10.25. This affected serial 
         port speed.

34       Citrix internal build: adds support for XenDesktop error messages
         in PNA; faster processing of lossy image compression; and improvements
         to the handling of colored cursors.

35       Fixes incorrect handling of full-screen PNA sessions when the default
         "Window" setting is also full-screen and adds "Display Name" to
         icabrowse output.

36       Adds German translations of PNA error messages introduced in version
         10.34.  Also adds configuration options to set the size of TCP
         send and receive buffers.

37       Adds an enhancement to make Seamless Windows interoperate with GNOME's
         "Focus Stealing Prevention" feature and fixes a failure to synchronize
         locking key state between client and server.  A new option, "-M" has
         been added to pnabrowse to select specific columns of output.

38       Corrects the size of the Program Neighborhood Agent credentials
         window when using Compiz.

39       Allows Microsoft Word 2003 to open files on read-only filesystems.

40       Fixes a shift-lock problem that occurs with Japanese keyboards.
         Allows Microsoft Word 2003 to open files on additional read-only
         filesystems.  Adds a configuration option, TransportReconnectOptions
         to control the auto-reconnect dialog and window retention
         during reconnection.

41       Ensure that the Program Neighborhood Agent authentication method
         defaults to "Prompt" as that is the most common method.

42       Fixes a problem on some recently-updated Windows servers: when the
         local Window Manager closes a window, the owning application is
         terminated, although it has other windows open.

43       Modifies the handling of SJIS-encoded ICA files for compatability
         with existing Web Interface servers.
