Comment 25 for bug 161000

I consistently obtain similar results:
- Can use Meta+Tab fine to cycle through applications, but not Alt+Tab
- Using Alt-Tab causes some applications (including Nautilus, FireFox, and LibreOffice, but not Krusader) to no longer response to mouse or keyboard input
- Shutting down and restarting the given application restores its responsiveness

System info (can provide more if needed; sorry I'm not sure what all I should report, I'm just kinda going with what others did):
Ubuntu 11.04
Kernel Linux 2.6.38-10-generic-pae
GNOME 2.32.1
Compiz
ATI graphics card
