the PythonWin IDE doesn't work properly when you're running programs that does their own Windows event handling. this is a problem with PythonWin, not with Tkinter or your program. to solve this, you can either 1) check if you can make PythonWin run the program in a separate process 2) explicitly run the program in its own process (using "python.exe" or "pythonw.exe"), from the command line. 3) switch to an IDE that runs Python code in a separate process (such as IDLE, Wing, and most other modern IDE:s). </F> -- http://mail.python.org/mailman/listinfo/python-list
