hi

My Programm constantly crashes with this error:
Assertion failed in DrawOpWin32.cpp, line 96 q != ERROR thats in bool Draw::IntersectClipOp(const Rect& r)
I can not reproduce the Error since it is an internetapplication that gets it's input from a server and the debugger does not give any more clues to the whereabouts of the problem.

I think however that it is probably related to a qtf-widget that is updated by a thread.

Does somebody know what to do to fix it?

Thank you very much

U++ only supports GUI in the main thread. If you need to update widget by thread, you need to use PostCallback.
