Startup Problem

I’ve been running opensuse 10.3 on a Lenovo X61 laptop for several months. Overall my experience has been great until I installed the last required update. For some reason when gnome starts it renders each window without window borders and I have to close an application to get to the application behind it. The only relevant message I’m seeing in /var/log/messages is:

gdmgreeter[3819]: Gdk-WARNING: gdkdrawable-x11.c:878 drawable is not a pixmap or window

Any help is appreciated!

Are you using any 3D effects? I saw this problem a while back when using Dekorator themes.
