Outlook 2003 Hanging and Conflict with IE

[Guest]

I run XP pro, IE 6 and Outlook 2003. I recently installed
the cumulative service pack for IE. Now problems I am
having include:

1. Send/Receive Error - get an error saying unable to
connect to network, although I am connected.

2. Outlook will not shut down cleanly - the outlook
process stays alive unless I manually stop it.

3. Outlook slows IE down...WAY DOWN. If I stop the
outlook process than IE behaves "normally" again.

Things I've done without luck:
1. DOS level virus scan (using McAfee)
2. In-box repair tool (was getting an error on shut down
saying ThorConnWndClass was not responding.

Any ideas out there?

Thanks,
Eric
