HELP!!! Desktop goes haywaire and taskbar items disappear

I had Premium running on my Intel dual core with 2 gig memory. I upgraded to
Ultimate and now my display goes haywire. Best description I can give is
that windows will jumble up within themselves and shadows of a window on top
of another will remain in a window below it when said top window is closed.
ALSO, my taskbar messes up to the point that everything disappears from it
until I roll my cursor over it then the objects begin to reappear but when I
click a button it selects the actual process to the icon to the left of it.
This is crazy. PLEASE HELP. I have to reboot my computer every 5 minutes to
fix this. Please email me at twitterp8ted@cox.net if you have solutions for
me.

Hey guys. Follow this link The Windows desktop may stop updating correctly after a Windows Vista-based computer has been running for an extended period of time if you are experiencing the same problem. Since 2/15/08, when I applied this patch, I have not had the problem again nor have I had to reboot my computer for any issue other than one I requested.
