Lets eliminate some variables by avoiding any IDEs.

Does it work OK when run from a DOS console?
Or if you just double click the file in Windows explorer?

If it does that means its some kind of interaction between the program
and IDLE. This is not unusual since IDLE is itself a Tkinter program
and although recent versions are much better behaved with Tkinter
it can still cause some strangeness.

If you still get an error running outside the IDE then we can analyze
it more closely. For that we will need the code, at least the function
that calls the dialog. And if its a subclass the dialog class too.
