I suppose the while loop runs in the main thread? That's not a good idea 
with Tkinter (and GUIs in general). I suggest using

http://effbot.org/zone/tkinter-threads.htm

as a template. The main difference is that instead of your while-loop and 
sleep() it calls the after() method which keeps tkinter in control so that 
it can still respond to events.
