About 5 times, after being on the net and without touching the mouse or keyboard, items get highlighted and action moves from one item to the next all down a section then the page scrolls up. If I close the page, whatever page I'm on does the same thing. At desktop, previous icon starts flashing (in this case, My Computer). When I click on start, and the closing box comes up, up and down it goes on the 4 closing options. Sometimes the mouse won't do anything...click and nothing so have to just shut down the computer and have it rescan. Thanks for reading this.
