MAPI catastrophic errors, undefined

After installing 2010 Norton Internet Security Suite I am now getting MAPI catastrophic failures, undefined error.  My system details are as follows:

 

  • Win XP Professional Version 2002 Service Pack 3
  • IE 7.0.5730.13
  • Dell Dimension 8300, Pentium 4 CPU 3.00 GHZ with 512 MB RAM

 

It appears that I only get the error when I leave my computer for a while.  It happens right at the time when I get a live update.  I do not have any screen saver running.

 

This is very frustrating because when this happens I can't open my Gmail contacts.  IE stops responding.  Everything else appears OK. 

 

 I have Outlook and Outlook Express installed but no longer use them.

 

I have done a search on this topic and have checked to make sure that I have the latest update.  This appeared to be a problem with earlier versions.

 

I really like this software but am frustrated!  Any help would be appreciated!
