Which version of Python are you using? Prior to 2.3, both IDLE and your
program would run in a single thread. As a result, IDLE's Tkinter-based
event loop would often (always?) clash with your script's event-processing
loop, bring evertyhing to a screeching halt. The version of IDLE that ships
with Python 2.3  executes your script in its own thread, avoiding this
problem.
