While I can't reproduce the problem you have since I'm on an older  
Python/Tkinter version, I'd say these last two lines are the problem: in  
Tkinter, Frame instances are not windows, but generic containers. Creating  
a Frame instance without having a window implicitly creates one, but you  
have to use some Tkinter internals to manipulate it, which is never a good  
idea. I'd replace these two lines with this one:

win = Tk()

which actually create the main window for the application as well as the  
underlying tcl interpreter, required by Tkinter.

Please note this must be done only for the main window, i.e exactly once  
in your application; other ones must be created as Toplevel instances, not  
Tk ones.
