Ok Experts -

This has got me stumped. About a week ago this started happening, and I thought originally it was only me. But turns out, it is happenining to all our systems, on 2 different networks! I really have no idea what caused it..  I'm wondering if it could possibly be from MS patches and software upgrades we've been pushing out.. to registry edits?

What happens is, whenever I lock a machine (not logging out), and then return to it, it will display the desktop. However, the taskbar will be gone and it will flicker (appears and disappears) and this basically causes the things (icons, windows, etc) on the desktop to attempt to adjust up and down (as if it's adjusting to you changing the screen height because the task bar appears and disappears). It will take a good 3-5 full seconds before it seems to finally finish loading the taskbar. And then everything's ok again. But again, EVERYTIME you come back from a locked account it will do the same thing again.

It's not a big deal at the moment, just an inconvenience.. but we've started to get some calls from users about this .. so I'd like to get this resolved as soon as possible.
The systems we have are standard Windows XP SP3 on Dell Optiplex 755's. They really don't have anything too special installed on them.. Office 2007, Adobe Reader, Flash, Java, McAfee
Weird thing is, it doesn't seem to do this when you do a fresh login.. only when you're logging back in from a locked machine.
And this doesn't seem to happen any of our 2003 Servers yet.

Any clues as to what is causing this??
