To ask the obvious, after upgrading you installed/updated winxp drivers for your chipset/graphics etc from manu sites and NOT winupdate?

There is no AV plugin in use?
The total sys memory is?
In OL you have a polling interval set for not less than 10 mins?

I have Outlook 2000 set up with three accounts.

After upgrading my system from Windows 2000 Pro to Windows XP Pro, every few minutes this happens:

1) there's a "ripple" on the video monitors
2) mouse and keyboard input is locked for between 5 and 10 seconds

It's hard to pin this on Outlook, but I believe that it happens during the automatic Send/Receive cycle. It seems not to happen when I close any open emails and close Outlook 2000 itself.

Any ideas greatly appreciated - so far "upgrading" to XP Pro has clearly taken my system down a notch or two in useability.

Thanks!
