I've done as you proposed (it's an IDE with virgin settings and without 
docking, just in case) and I've attached two debug outputs. In both 
cases I have started the IDE and opened the File Open dialog with 
Ctrl+O. In the "normal" case I've closed the dialog using "ESC" in the 
"problem" case I've first used "Win+k" to switch to a different window 
of the IDE (which wasn't moved to front of course, but the windows 
manager nevertheless marked the windows as focused) and then I've closed 
the dialog. After this forceful switch the behavior described in my 
original mail appeared (reproduceable).

I've also checked whether some output happens directly after using 
"Win+k", but this is not the case...

Regards,
Sven
