Okay. So number one problem is I have to type slowly, or my sentences look like this- "elo ow are yo ad wha is going o?" My laptop has touch sensor buttons at the top too that don't seem to work at ALL. Or the touch pad at all. It's a dell with vista. I have done virus scans and nothing has came up. I usually use a cordless mouse but it has never affected it before. And if it makes a difference I am on it up to 3 hours a day. unlock iphone 3g
