hi. i joined these forums because i have a problem with windows update. i forget all the details but when i go to download updates some wizard pops up for service pack 1. all goes well, then my mouse arrow freezes. i have to shut down my computer. ctrl-alt-del doesn't work. this has happened 3 or 4 times.

any idea what causes it, or, better yet, any idea what i can do to keep it from happening again? i'd like to get these updates.
thanks.
