gnome cannot keep theme

Hi, I am using gnome 2.X in opensuse11.4. I found that each time I log off ,the gnome theme changed automatically to the default one. When I right click the mouse in the desktop, it changed back again to my setting.

How to fix this bug?

Are you running desktop effects? Usually, when I run into graphical issues with Gnome, it seems to be related to compiz issues. I turn them off and the issue goes away.
