Don't run GUI programs from within IDLE is the best advice I can give.
It's a lot better than it was and at least they run now but IDLE still 
catches
too many keystrokes and events itself and its a lot safer to test GUI 
programs
by running them outside IDLE. Just double click the file in 
Explorer...

Or to see the errors run it from a DOS prompt.
