IDLE does not start on WinXP

Please excuse the following mailing, I do not have access to a news server
and cannot post to comp.lang.python.

I recently installed Python 2.3.4 on WinXP. Command line interpreter works
fine but the IDLE GUI will not start. When run from a commandline I get the
following traceback. Both WinXP and McAfee firewalls are disabled. Any
suggestions would be appreciated.

Since the traceback indicates that the error arose in a command related to
socket communication, I think the first thing you should check is your
firewall software. You should allow connections to 127.0.0.1 (the loopback
to your own machine). (If you've installed XP Service Pack 2, you now have
firewall software whether you knew it or not.)
