hello and thanks,
the following code is a small sub-snippet from a program i am trying to
learn/write.
the source code will run fine the first time inside of AP(active python).
if i press the run button again i get the following error.
why, o why?
what changes inside of ap from the point before i run this code and the
point after i stop running the code.
perhaps a path issue?

extra facts:
if i run the code from the windows nt command line, everything is ok.
if i run the code from komodo, i can run it over and over, no problem.
if i run the code from ultraedt, a windows editor, everything is ok.

thanks,
dave

code:
------------------
from Tkinter import *           # The Tkinter package
import Pmw                      # The Python MegaWidget package

master = Tk()                   # build Tk-environment
g = Pmw.Blt.Graph(master)       # make a new graph area
