Black box when mouse hovers over icons in Gnome and v11.1

I finally upgraded from 11.0 to 11.1. I’m running Gnome 2.24 (the Gnome stable repo is enabled) and basically followed directions from Upgrade/Unsupported - openSUSE . After disabling the ridiculous desktop icons and login sound I was rather pleased. Everything had worked flawlessly except for one thing I can see. When the mouse hovers over buttons I get a black box instead of a text box.

Any thoughts on what I’m missing?

Thanks!

Problem resolved after switching to another theme and icon set.
