When you try to restore the application, the window disappears, leaving no trace of the application. Reproduction In this scenario, there are two server farms at separate sites?Farm A (front-end) and Farm B. Users are based in another site. Users launch a published Internet Explorer on Farm A. They connect to the Web Interface logon page on Farm B. They launch the applications that are published only on Farm B. They minimize the application to the taskbar. When restoring or maximizing the window, it ?disappears,? leaving no possibility of regaining control of the application. The session stays active in the Presentation Server Console. You can see the session on the Connection Center. Note: This issue only occurs when using seamless windows. Fixed size windows do not experience this problem. Resolution Use the seamless flag 0x80000 on the front-end servers of the first farm. Note: Verify the minimum hotfix level required for this flag to work. More Information CTX101644 ?
