Darren,
I tried "idle -n" and got the same result:
Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on
win32 Type "copyright", "credits" or "license()" for more information.

investigate it
with a google search (thats how I learned about the problem
and the solution
for idle).I suppose win32pipe is part of pywin32. If that is the case,
I dont think I
can support using it; we are trying to eliminate
dependencies, not add to
them. Subprocess is acceptable because it is part of the
python-2.4 standard
library and we were able to add it to the mpl tree for older
versions of
