I am using python 2.1 on Win98.
I have some experience which may be a clue of this problem.
(Note: I am new to python; I am not sure if what I am writing is true.)

In conlusion, I suspect that to use pythonw.exe instead of 
python.exe to launch from dos box is better.

My experience:
Start python.exe and then do os.system('myprog.exe') 
from idle-shell window will cause hang.
Here, myprog.exe is a tiny console app in which 
simple stdin and stdout have been used.
Instead, start pythonw.exe and do the same thing,
it worked properly and I was able to close idle without
