Darren,
I prefer using PythonWin to IDLE. Any ideas how to solve the
subprocess.Popen() problem using PythonWin? What about using
"win32pipe"?

I forgot to mention, you may be able to avoid these errors by starting
idle
with the -n flag.

In both the IDLE & PythonWin (my default my using pylab) shells it
fails... but not from the python shell...

Darren,
I prefer using PythonWin to IDLE. Any ideas how to solve the
subprocess.Popen() problem using PythonWin? What about using
"win32pipe"?
I don't know how to solve it for pythonwin, maybe you could 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
python.
