ASUS touch pad messing up?

Well, my ASUS touch pad seems to become more of a hle than helpful. Sure I can use a mouse to move around, but I don't always care to use it. And my touch pad would someones make it seem like it was double touched, so it would shrink or enlarge the page, or just in general it would be difficult to move. I don't know what the problem is, it's not like I'm my finger too quickly. Anyone have problems with theirs?
