I'm glad to hear you figured it out, but I will say one thing. Tk::Wizard isn't used very often at all, so don't expect too many people to know about it. As a matter of fact, you are the first Wizard question I've seen here in years. So when you use these GUI-makers, expect to run into troubles, that occur because of the hidden complexities of the GUI-designer. That is why most Tk authors always stick to the basic widget set, it's a little more work, but you have more control.
