The problem is that PythonWin uses MFC-based windowing, and runs 
programs as a part of the same process that the IDE itself runs in.

This means that there are conflicting requirements for windowing, and 
this can lead to PythonWin getting confused enough to crash and die.

To avoid this you need a development system that uses a remote debugging 
technique - WingIDE, for example, can successfully debug programs based 
on Tkinter, wxPython and other graphical toolkits, because the programs 
it runs are run as separate processes.
