You don't really say what your code does or if it uses a GUI toolkit
and if so, which one. But my guess is that you are using some kind of
GUI and its GUI and IDLE's are clashing somehow. I see this sort of
thing with some of my wxPython programs from time to time, although
IDLE usually just crashes with no error message.
I would recommend using the command line or something that can open it
in a completely separate process, such as Wingware's IDE.
