Q200820 Second taskbar above existing taskbar when using the RES Subscriber and Citrix hotfix
A second taskbar will be displayed when starting a seamless RES PowerFuse published application using the RES Subscriber and the RES PowerFuse session uses the "Microsoft Windows Shell". The second taskbar will be positioned above the original taskbar. The second (non-functional) taskbar will disappear after a refresh of the RES PowerFuse session.
Cause 1 - Citrix Hotfix XE104W2K011 is installed
95% probability.
Citrix Hotfix XE104W2K011 is installed.
http://support.citrix.com/kb/entry.jspa?entryID=6275&categoryID=120After closing the modal dialog boxes of certain published applications in the seamless mode, the focus will occasionally be aimed at other windows on the client desktop, rather than at the application that launched the dialog. The focus will be reverted to the application when clicking the seamless application title bar.
Applications affected by this issue use a zero-sized window at coordinates (0, 0), to hold focus between the time the modal dialog closes and the time the application window is re-enabled. The seamless code will recognize this window as invisible and therefore does not send seamless protocol messages to it.
Solution 1.1 - HOWTO: Disable Seamless for the entire Citrix Webinterface
38% probability.
Change the "Window Size" setting for the published application from "Seamless" to e.g. "Full Screen".
If the Citrix webinterface is used, the client connection size will default to "Seamless". You can change this default setting by modifying the default ICA file located in c:\inetpub\wwwroot\Citrix\MetaFrame\conf\ (the location of the file can differ, depending on the name of the Web site).
This option forces every application to start in Full Screen.
For Citrix Metaframe Presentation Server 4.5:
1) With the editor of your choice, open the file default.ica located in c:\inetpub\wwwroot\Citrix\MetaFrame\conf\ (the location of the file may be different, depending on the name of the Web site).
2) Add the following lines under the [Application] section:
TWIMode=Off
ScreenPercent=Full screen
3) Save the file.
For Citrix Metaframe Presentation Server 4:
1) With the editor of your choice, open the file default ICA located in c:\inetpub\wwwroot\Citrix\MetaFrame\conf\ (the location of the file may be different depending on the name of the Web site).
2) Add the following lines under the [Application] section:
TWIMode=Off
DesiredWinType=7
3) Save the file.
Solution 1.2 - Solved In RES PowerFuse 7.03 CF
38% probability.
This issue has been resolved in RES PowerFuse 7.03 CF.
To check whether you are running the correct version of RES PowerFuse 7.03 Edition 2005, do the following:
1) Launch Real Enterprise Manager.
2) Select Help > About... from the Start menu.
3) "Revision" should display "CF" or later (located below "StartLevel").
If you are not running revision "CF" or later or if the revision is not displayed, download and re-install PowerPack 7.03.
Solution 1.3 - Add Citrix "use owner window instead of parent" registry key
25% probability.
Add the following registrykey:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI]
"SeamlessFlags"=dword:00000020
Enabling this flag specifies that the Owner window of the window specified will be determined by using the GW_OWNER parameter instead of the GWL_HWNDPARENT parameter. This may be necessary if some application windows do not use the same window as both Parent and Owner window.
