Permission Denied With os.rename On Win32

[John Abel]

I have a small script, that moves files around.  I wrote and tested it 
with 2.2.2 and 2.3b1 on RH9 Linux, with no problem.  I've come to run it 
on my Win2000 machine, and I keep getting Permisiion Denied errors.  
I've modifed the code so it does a copy, and then an unlink without 
success - the unlink fails.  Has anyone come across this before?  I've 
done a search of the archives, and it pops up a couple of times, but 
usually in association with threads, which I'm not using.

Any pointers would be much appreciated.  Thanks.

John
