Issue(s) Resolved in this Hotfix

Caution! Several items in this hotfix may require you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved . Use Registry Editor at your own risk.

1. Users may encounter the following issues when switching focus between applications in seamless mode:

* Error messages appear stating "Invalid menu handle"
* User-invoked popup menus, such as those appearing when right-clicking window controls, disappear unexpectedly

The issues occur because Presentation Server closes certain types of windows if they appear to become unresponsive to change in focus events.

[From PSE400R01W2K3006][#127287]

2. The FlashWindow and FlashWindowEx APIs fail to make the taskbar icon flash in seamless sessions.

[From PSE400R01W2K3030][#127379]

3. Manually set printers fail to be set as default printers within sessions. Also, default printers are not set when using workspace control to connect to an existing session from a different client.

[From PSE400R01W2K3053][#129339]

4. After upgrading to Presentation Server 4.0 and Version 9.x of the Presentation Server Client, applications that create windows outside the visible area of the desktop may continually take focus over applications running locally if run in seamless mode. To avoid the issue, set the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI
Name:SeamlessFlags
Type: REG_DWORD
Data: 0x20000

[From PSE400R01W2K3053][#130862]
