When running a script using Python 3.0.1 I get an error saying that
tkinter.messagebox doesn't exist. However when I run the same script
from within IDLE, it works fine.

This has led to my thinking I'd fixed the Python 2.6/3 compatibility
errors while testing in IDLE, but had end users say it didn't work.

Why do you think this is a bug? You need to import tkinter.messagebox
explicitly for your program to be correct. That you could do without
inside IDLE is only because IDLE had already imported that module.

Closing as "won't fix".
