IDLE does not start on WinXP

[George Carman]

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.

C:\Python23\Lib\idlelib>idle.py
