Hi, first of all here's my system:
Linux 2.6.21-1.3228.fc7 #1 SMP Tue Jun 12 15:37:31 EDT 2007 i686 i686 i386 GNU/Linux

The problem I'm having is that my system hangs every time it runs a qt application; it hangs even when trying to run qtconfig. I first discovered this problem when trying to run texmaker. The hanging happens right at the point when the window has come up and before any widget is shown; in fact, the places where the widgets should be are just white. And the system would be frozen to the point where it would require a restart.

Does anyone have the same thing happened to them? Any help would be appreciated.
