Hi All,
I am experiencing a strange behavior with an OpenGL window.
I open several windows, one of which is an OpenGL window.
If the windows do not overlay each other everything works fine.
If I move one window on top of the OpenGL window than the GUI hangs and no events are processed. I can't even close the application.
If the OpenGL window is updated with redraw() method then the GUI starts to work again.
Any suggestion on how to solve this problem?
Trace in a debugger, see if its blocking in your own code.
Kinda sounds like it might be blocking in one of the event handlers..
Supply a stack trace during the hang, or try to make a simple
compilable example that replicates the problem.
