I'm running Suse 9.1 pro. All of my tooltips on ALL applications are blank. When you pass your mouse over them, the tooltip appears but there is no text... it's just a blank box. This happens for all my applications on the whole system.

I really didn't care at first, but I started using The Gimp, and I almost can't live without tooltips on this app because there's no other way to determine what the icons do without clicking them first.

I have looked at Control Center where you can turn tooltips off and on, but mine are on already, so I can see no other configuration for these. I have also googled for this problem but it seems like it's just me.

Any ideas?
