Hi,
what's the **kw stand for, used for? What does it mean?

Uh, not really, no. I'm very new to GUI. So you're saying that If I make the
class actually do something (I edited and example in:
An into to Tkinter, Fredrik Lundh).

Aaag. I'm confused... I just tried you changeQuote example with out the above
stuff... didn't work. My error message:
AttributeError: 'NoneType' object has no attribute 'config'
so I edited it a little, still didn't work (same error). I tried the class
Main(Frame) and didn't get it to work either. Do you think you could make it a
little bit simpler? If you can't that's ok, I'll try to study it more.
Thanks,
Joe
