Outlook not responding

[Numberone]

Hello all,

I have a user with an IBM NetVista running Outlook XP (and
Office XP) and McAfee 7.0. Whenever both are running, and
the user switches to other apps, then tries to return to
Outlook, Outlook does not respond. I have tried:

- re-installing both Office (and Outlook) XP and McAfee.
- disabling "Scan Email..." within McAfee.

Any suggestions or comments would be greatly appreciated.

Thanks,
Numberone
