I got an old tablet from a pal of mine, and it worked fine on his compy. I got the driver and everything, but for some reason, on my computer, the sensitivty is shot to hell, and it does this weird thing, that looks like I tried to draw a straight line by placing my paper over a brick wall (basically, it gets all zig-zaggy for no reason).
Anyone with some tablety know-how, I need help!
