Citrix XenDesktop 5.6 FP1 issues fixed in this release

The following issues have been fixed since the previous release of this product. For information about new features and system requirements, see Citrix eDocs, the Citrix Product Documentation Library.

  1. Configuring the printer policies might take up to eight minutes per policy change. As a result, the console might become unresponsive while changing the printer policy.

    To enable this fix:

    1. Install the Group Policy Management Console hotfix (GPMx150WX86003; GPMx150WX64003, or their replacements) that contains Fix #257255.
    2. Migrate the old printer policies to the new printer assignment policy using a PowerShell script, available for download in Knowledge Center article CTX132168. However, some of the new printer policies might not require any action.


  2. Under rare conditions, pressing the Num Lock, Scroll Lock, or Caps Lock keys while a virtual desktop session is in the process of logging off can leave the LED indicators out of sync with the actual on/off state of those keys on the endpoint.


  3. Session printers are not deleted when connecting from different end points that are subject to different printing policies. The issue occurs because the Citrix Print Service, CpSVc.exe, does not honor policy changes during session reconnection, including the deletion of printers that are no longer required under any newly applicable policies upon reconnection. This enhancement introduces support for the following registry key that, if set, enables the deletion of session printers upon reconnect if policies dictate that they are no longer required:

    HKEY_LOCAL_MACHINESoftwareCitrixICAPrintingSettings Name: DeleteNetworkPrinters Type: REG_DWORD Data: 1 (to enable deletion of unnecessary session printers)


  4. When hiding and restoring a mouse pointer repeatedly in a virtual desktop session, the endpoint might become unresponsive or the mouse pointer might fail to follow the user’s mouse movement consistently. Hiding and restoring the mouse pointer is common, for example, in online collaboration applications, such as Citrix GoToMeeting, where users’ roles may alternate between those of presenters and attendees.


  5. Attempts to type the password to unlock a locked Virtual Desktop Agent with Local App Access enabled fail until you switch the Desktop Viewer to window mode.


  6. When using Citrix Receiver 3.0 within a virtual desktop session, attempts to launch XenApp published applications fail and the following error message appears:

    “This version of Citrix Receiver does not support selected encryption. Please contact your administrator. [Error 1029: Invalid DLL load].”


  7. When using Receiver for Windows 3.0 and Virtual Desktop Agent 5.5, opening and closing multiple tabs in Internet Explorer 8 running on a Windows 7 Virtual Desktop Agent can cause Internet Explorer to become unresponsive.


  8. When reconnecting to a disconnected session, the session volume defaults to 100% even if the volume level was modified before disconnecting.


  9. On systems with HDX 3D Pro Graphics enabled, the mouse pointer can display the following, irregular behavior: When you move the pointer to the edge of an Internet Explorer window, the pointer correctly assumes the shape of a double-ended arrow designed to let you modify the width of the window. However, when you move the pointer back over the Internet Explorer window without touching any of the window elements such as hyperlinks or buttons, the pointer does not revert to the default shape. Instead it retains the double-ended arrow shape.


  10. Installing XenDesktop 5.5 Virtual Desktop Agent prevents embedded Windows Media clips from playing in Internet Explorer in Citrix Receiver, RDP, and VM Console connections.


  11. When using an RDP to connect to a virtual desktop session, users can experience delays while logging onto or unlocking the desktop.


  12. A Citrix Group Policy “Userenv error 1085” occurs if a user logon attempt occurs before Terminal Services starts.


  13. Windows Media Player can continue continue rendering audio after clicking the Stop button towards the end of the stream.


  14. Clicking the Windows Media Player progress bar in a multimedia file does not consistently honor and resume playback from the new position in the file.


  15. With client drive mapping enabled, copying multiple files with non-ASCII characters in their file names can result in corrupted copies or in identical copies with different file names.


  16. The presence of a browser security plug-in and a keyboard encryption/interception module on certain banking Web sites causes single letters typed in the User ID text box to appear twice.


  17. This fix improves logon speeds previously delayed by the picaSvc.exe service.


  18. Setting the system locale of a Virtual Desktop Agent to Turkish can produce a 1030 Error and prevent users from connecting.


  19. Changing the Windows theme or desktop background can render the Virtual Desktop Agent unresponsive.


  20. A deadlock in HostMMTransport.dll during shutdown can cause audio playback to stop unexpectedly.


  21. HostMMTransport.dll, when dereferencing a null pointer, can cause applications to exit unexpectedly.


  22. A race condition between the listener and the reader threads can cause audio playback to intermittently fail.


  23. HDX RealTime Webcam Video Compression might fail to work with Cisco WebEx.
