Wow! That's elegant code. You're way ahead of me on TK coding, and I've learned a couple things from your code already. I didn't test all choices, but the basic action works in P4 and P5 on Windows. Incidentally, you've found the key to making a script work in all forms. This part right here: def Quit(self): ~self.master.destroy() ~self.master.quit() I had found a much more clumsy way to make scripts work in both, but your way is simple and clear.
