Description of problem:
I recently rebooted my machine after a kernel update and now I am unable to
cycle between windows using Alt-Tab like I used to be able to.  It has been a
while since a reboot, so it could be unrelated to the kernel update, but that
was the last thing that I did.

New accounts do not seem to have the same problem, but copying all the files
from a new account into my home directory did not fix the problem.  

Version-Release number of selected component (if applicable):


How reproducible:
Sometimes

Steps to Reproduce:
1.log into one of my older accounts
2.type alt-tab
3.
	

Actual Results:  the title bar of the active window flashes as if it was going
to change, but nothing actually happens - the active and raised window does not
change.

Expected Results:  the next window should come to the top and become active.
