subprocess problem on Windows in IDLE and PythonWin

[David S.]

Python 2.4 on Windows XP
In the python command-line the following works fine:
[color=blue][color=green][color=darkred]
>>> from subprocess import *
>>> p = Popen('dir', stdout=PIPE)[/color][/color][/color]
[color=blue]
>From within IDLE or PythonWin I get the following exception:[/color]

Traceback (most recent call last):
File "<pyshell#1 3>", line 1, in -toplevel-
p = Popen('dir', stdout=PIPE)
File "c:\python24\li b\subprocess.py ", line 545, in __init__

TypeError: an integer is required

Note it works fine on Linux also. I tested it with[color=blue][color=green][color=darkred]
>>> p = Popen('ls', stdout=PIPE)[/color][/color][/color]
.... and had no trouble.
