Try using CTRL/Break in Windows, that will usually break into a
console-based program even when CTRL/C isn't regarded as urgent enough.

I suspect that Mike's problem is more that he's writing graphics output into
a Tkinter window from a console-based program, and he wants some way to
indicate to the program that it should stop what it's doing before it's
finished, and wait for further input from the user. Right, Mike?
