Help running Piddle in Interpreter on a Mac.

[Louis M. Pecora]

Whenever I try to use Piddle plotting in the Python Interpreter I get
the following message:

Traceback (most recent call last):
  File "Drive:Applications:Python 2.2:Lib:site-packages:piddletest.py",
line 398, in ?

"Drive" is my HD name and Python is kept in the "Applications" folder. 
This problem happens even with the original piddletest.py module which
works ok until attempting to open a plot window -- meaning I don't get
far.  Then I get the above msg.  

I am running Python 2.2 on a Macintosh G4, system 9.1.  Same problem on
my G3 and PB.

Anyone have success in getting Piddle to work with the Interpreter on a
Mac?  Any help appreciated.
