--- Comment #17 from Eric Mullins emwine@earthlink.net 2008-07-15 01:16:15 --- (In reply to comment #16) Verified. I found a utility to help duplicate the issue called 'cmdow'.
http://www.commandline.co.uk/cmdow/
I opened up mshearts, switched desktops, used cmdow to get the hearts window id, then used cmdow to set it to always on top. It disappeared immediately.
CMDOW also allowed me to get the window back by simply moving it to 0 0.
Here's a log of what I did: [launched mshearts from a desktop icon] 503 wine cmdow.exe [obtained window ID of mshearts as 0x03007a] [moved the hearts window to another desktop] 504 wine cmdow.exe 0x03007a /TOP [hearts window disappeared] 505 wine cmdow.exe 0x03007a /NOT [nothing obvious happened] 506 wine cmdow.exe 0x03007a /MOV 0 0 [hearts appeared on the active desktop]
