> I'm using python 2.7.2 with Tcl/Tk 8.5.11, and I'm using a lot of ttk themed widgets in the UI. The layout is a ttk.notebook with a number of frames per tab; some tabs have frames that are created/destroyed based on user selections.
> Occasionally when I execute the program, either within the debugger or by itself, the entire window flashes rapidly and continues until I terminate the script. I had noticed that certain dimensions in the frames that are dynamically replaced caused the flashing whenever I caused the frames to change, and by making small adjustments it seemed that I had eliminated the problem.
> However it still happens occasionally--but not repeatably on my system--and now I've gotten a report from a tester that it flashes on his system when he hasn't done anything that causes frames to be created. As soon as he clicks on a certain button widget the entire UI starts flashing. The same scenario doesn't cause it to flash on my system.
> Does anyone know what causes this? Any suggestions for tracking down and eliminating the problem?
