[Tkinter-discuss] Returning control from a toplevel window

[Guido Carballo-Guerrero]

Wayne, Michael;

This is a sample code that shows what I'm doing. As you can see, even if I don't have a while loop, the picture is not being shown. Am I missing something? What is wrong with my code that I can't open and show the picture in the new Toplevel window?
