I tried to modify pilview.py to  actively increase th color
every second using Python1.4b3, PIL 2 (temp release), tk 4.0, and
kernel 2.0.6.  I added two self.after(1000, self.cmd_light) 
 statements - one after the Pilview init and one at the end of 
the cmd_light statement.  See the Pong demo in tkinter examples.
The self.after in cmd_light always fails with self.tk_createcommand
something about cannort create name.

Does anyone have any ideas or any suggestions where to look?  I
am busy researching the problem but PIL, python, Tkinter etc
are all new to me so it is a very interesting learning experience.

If necessary I can send out the modified pilview.py.
