[Tutor] Problems with Python 3 and Tkinter

[Peter Anderson]

I have just re-installed Python 2.5.4 and the calculator.py script runs 
correctly using the original script (even when no value is entered in 
the data input field - the error dialog displays correctly). This is 
very frustrating!

Clearly there is something different in the way Python 3.0.1 is handling 
Tkinter and tkMessageBox.

Regards,
Peter
