You didn't mention where you got the ScrolledText widget, but apparently 
you did a "from ScrolledText import ScrolledText", isn't it? If it is, I do 
have the same problem: apparently, the creation or gridding of the 
ScrolledText tries to pack something in the "main" widget, which results in 
program hanging.

I would advise not to use the ScrolledText widget from the ScrolledText 
module since it is obviously not so well designed... Either use the Text 
and Scrollbar widgets from Tkinter (you'll have to bind them to each other 
explicitely, but it's quite easy), or use the ScrolledText widget 
from PMW (Python MegaWidgets) that you'll find at:
http://pmw.sourceforge.net/
You'll also find in PMW a great deal of other very useful widgets.
