I'm using a Logitech performance laser wireless. http://www.newegg.com/Product/Image...0000264 Black Cordless Ergonomic Desktop Wave I keep getting dead spots all over my desk. Batteries are fresh. Got the USB plugged in the back of the computer, not into the cord that plugs into the computer. (See pic) I've tried running it into the USB cord and still have dead spots. Playing poker can be a pain when I can't click one of the buttons. I multi-table a lot, so I need something that's going to work great. I've always liked Logitech but would be willing to try another brand if it's better!
