Problems logging out

[MHR <mhullrich gmail com>]

I just started having some trouble logging out from my CentOS 5.1
system.  For some reason, when I try to log out, the log out program
hangs.  This happens whether I click on the "Log Out" button or wait
for the timeout.  When I looked, I somehow (I forget how) found out
that the clock applet would not go away.  However, when I separately
killed the clock applet, the session still refused to log out.  The
only way I could get the session logged out was to kill the
gnome-session process (works like a charm).

I thought this might be related to the new xorg server update problem
from upstream, but the new one doesn't fix it (not surprised).

Any ideas?

Thanks.
