mine didn't change either... i'm wondering if it's because of ageye's g-alarm? i'm sure a lot of us use that and i'm wondering if that's the culprit since it has some weird "fix windows alarm bug" thing when first installing... i will try the fix posted above, thanks.
dtndvm, any links to where you got it from???
edit: a search for what dtndvm posted led me to this microsoft page:
