error exiting mainloop in tkinter

[Newt]

Whilst not very helpful, it ran fine for me. I had to do a slight amount of
formatting as all the tabs/indentations had been lost in your post. (I'm
running 2.2.1 on XP)

Where abouts did the error occur? Did you get the window up, with a single
button?  Was it a windows error and not a python error? Do any other Python
applications work? Can you close the application using the X button on the
top right of the window?
