Hi Brian,

Thanks for the recommendation on wxPython. I'll check it out. It's
not like I've lost a ton of time learning Tkinter. That does bring up
the question of why is wxPython better than Tkinter, though.

The basic idea you recommend is exactly what I want to do, but the
problem I'm having is actually changing the buttons' state. I have
them initialized to inactive, and I'm checking the input fields for
data. My problem is that I don't know (and can't find an example
anywhere) how to change the state of a button that has already been
packed.

I'll check out wxPython, though. It may be that I'm just using the
wrong GUI extensions...

Thanks again,

Jamey Saunders
