I'd like to report a bug/unimplemented feature.
That is Alt-Tab between windows programs running in WINE (eg Dev-C++) and linux programs (eg Adobe Reader

The two programs I specifically mentioned to give you more info!
Alt-Tabbing from Adobe Reader to Dev-C++ 'prints to the screen' a very small amount of the top bit of the window.

Alt-Tabbing from Dev-C++ back to Adobe Reader doesn't pose a problem.

So please fix/add this feature in your next release.
Thanks in advance,
Panarchy
PS: The OS I am using is Super Ubuntu.
