I've had my Dell Studio 15 laptop for about a month now and everything's worked fine until now. I was just using it earlier today and it was fine but now the scrolling feature on the touch pad doesn't work. When I run my finger down the side to scroll, the cursor even changes on screen to show that it's scrolling but it's not working at all. I have the driver updated to the latest version. If anyone knows what could be the problem, please let me know. Thanks.
