I have a mian PC and a laptop. If I use the laptop's trackpad, everything works fine on both systems. If I use my main PC (which is the one I want to use) and try to scroll over to my laptop, the cursor instantly zips across the screen and sticks to the right side. I want to use my main PC because of the nice mouse and keyboard I have. But once I try to move over to my laptop the cursor just instantly moves to the far right edge. I can still see and move the cursor up and down and even click the far edge of the screen. Assuming, since things are working fine when I use the laptop trackpad and I only get a failure when using my main PC, that my main pc may have a settings issue or something.
