Strange... I've noticed that two problems with my PC magically fixed themselves. Certain items in web pages (such as Flash animations and form controls) used to redraw incorrectly when scrolling the page, sort of vertically blurring themselves with multiple copies in the wrong spot. Fixed. Also, for quite a while my system has never prompted for what to do when new media was inserted or attached to the system (such as CDs and my camera's USB connection) even if I set the properties of that device to prompt me for what to do. Now it's prompting me again.
