Hey folks, I thought one of the genius types here could help me out with my little problem. The "z" key on my keyboard is stuck, I think. Looking at it, its looks fine. But when I try to hit the key, I have to sort of hit it in the top right corner, or press down very hard to get it to work. Does the key pop off so I can see what the problem is? I didn't want to go pulling around and snap the thing off. Any ideas??
