Yes, I was back to VGA during the upgrade and applied the latest (Matrox) drivers after Windows XP was up.

Assuming by AV you mean AntiVirus, I have Norton SystemWorks (I think same as before upgrade; I upgraded from the 2005 version to the 2006 version)
I have 2GB of memory
the polling interval is exactly 10 minutes (same as before upgrade)

I should mention that I normally run Outlook from a .CMD file at Windows start-up. The .CMD file saves my auto-archive file and lets Outlook start a new one, once every six months. I'm wondering if somehow Outlook could behave differently when run from a .CMD file, though I've made no effort to correlate this with the disruptions. And of course, this hasn't changed, either. Nothing fancy, just:

START "Outlook" /MIN C:\path...\Outlook.exe

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!
