When I use my Microsoft Explorer Mouse on my ASUS laptop, i put the cursor in the top right, then I take my mouse and move it horizontally from right to left, the cursor on screen angles at a distance that is close to the middle left of the screen. I tested it over and over, I know when I use it, it still doesn't "feel" right. I use another mouse that is not wireless and it works just fine. This mouse also works just fine on my Dell laptop. I installed the lastest version of Intellipoint (8.2) and have all drivers good. I don't know what the problem is. Also, I got 2 of the same mouse and they do the same thing.
