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:

From within IDLE or PythonWin I get the following exception:

Traceback (most recent call last):
File "<pyshell#13>", line 1, in -toplevel-
p = Popen('dir', stdout=PIPE)
File "c:\python24\lib\subprocess.py", line 545, in __init__
(p2cread, p2cwrite,
File "c:\python24\lib\subprocess.py", line 605, in _get_handles
p2cread = self._make_inheritable(p2cread)
File "c:\python24\lib\subprocess.py", line 646, in _make_inheritable
DUPLICATE_SAME_ACCESS)
TypeError: an integer is required

Note it works fine on Linux also. I tested it with .... and had no trouble.
