Netizens discover strange phenomena in Vista and XP: CPU suddenly surges to 100%

A friend saw a post on a certain forum which claimed "a bug in XP has been discovered", and said "those who don't believe it can try it out". The general meaning of the post is: "Use a mouse with a scroll wheel to quickly and continuously scroll up and down on a web page, and at this point, the CPU usage will rapidly rise to 100%." According to the poster, this situation will occur regardless of whether the user is using Windows XP SP1 or SP2.
