Followup to my notebook issue of flashing window on the start bar:

I did a system restore to about a month ago --right before an HP update-- and all is now well. Bah humbug. In addition to the flashing window, my screensaver no longer came on after the 20 minutes I had it set for, until this restore fixed that too. What the heck??? I had also installed some upgraded MusicTime software which may have changed some settings after the HP change. Is it possible that HP or MusicTime changed so many system settings on me, or do you think it was something else that happened in the interim?
