IDLE does not start on WinXP

[Snake]

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

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