I'm just trying to find out if my laptop is behaving like everyone else's. As with most people, I take notes in portrait mode. The pen's sensitivity and resolution is surprisingly great anywhere on the screen except half way down the screen in the side with the hinge. As the pen makes its way over to the edge, it starts getting jittery and stops tracking my motions as well. Is this a common problem? I'm a math major, and every often, I have to make small fairly precise motions. They work everywhere but one edge of the screen, and this can cause problems with my notes. Attached is an example of my problem. I'd appreciate it if anyone could respond so that I can know if I need to call Gateway and have them replace my screen.
