Here is a little more information - The up down 'wheel' on my touchpad works intermittently. The left and right mouse buttons work just fine, it's just the scroll that doesn't work consistently. The scroll comes and goes everywhere. Sometimes it works in e-mail, sometimes not. Sometimes in WP or on the Internet, sometimes not. If it starts working, it stays working until the next time I turn the computer off. It's not consistent anywhere. I have an HP pavilion ze5375us using Windows XP Home. Thanks.
