Computer locks up when running valid stand alone Tkinter file.

[jim-on-linux]

py help,

The file below will run as a stand alone file.
It works fine as it is.  

But, when I call it from another module it locks 
my computer, The off switch is the only 
salvation.

This module when run as a stand alone, it will 
open a jpeg image and add a vertical and 
horizontal scrollbar to the canvass.
That's all it does.  

Replace the img9.jpg file with one of your own, 
put the image in the current working dir., and 
run.

If you think you can help, I would appreciate it.
