Subject: Windows : Emacs frame stays on top after Alt-Tab
Date: Thu, 31 Mar 2016 11:17:26 +0200

GNU Emacs 24.5.1 (i686-pc-mingw32) of 2015-04-11 on LEG570

On Windows (7 Professional), after (?) switching from a Aero Desktop Theme back to a non-Aero Desktop Theme,
pressing Alt-Tab will switch application windows, but the Emacs Window ("Frame"?) will stay on the foreground, which is wrong behaviour.
Only after exiting and restarting Emacs is the correct behaviour restored again, and Alt-Tab works as expected.

I saw some discussions on the use of SetForegroundWindow and some bug reports that might relate to this.

In general I despise applications that use SetForegroundWindow, because almost all of them fail to do what the user wants, because of lack of knowledge of other active applications and the user's intentions.
This bug report is also an example of such behaviour.

Why not totally remove the use of SetForegroundWindow (except maybe for sys_kill and some places that try to fix "bugs"), or at least make it customizable so that I can disable it?
