Screen Physically Clicks.

Hey all. I purchased a 2.4GHz BlackBook around May of last year. So far, I love it. With in the first week I noticed that the screen would click, on the right side, as in, you could push the screen in, like it wasn't connected to the frame. It only happens on the right side, no where else. It really hasn't been a problem, as mostly the computer just stayed on my desk, but now that I'll be going off to college soon, I'm wondering if I should take it up to the Genius Bar, and see if they could do anything, or if they would say "well you probably did it, as you've had it for almost a year." Also, this might be my "I like new things" side showing, but if they were to be able to repair it, would I have any shot at paying the difference for a new/refurbished Aluminum Macbook, of the same spec list?

Thanks,
Jesse

I have this same exact problem its on the plastic rim of the screen right side about 3/4 the way up the screen. (I also have the black macbook)

Yup, I'd definitely have it looked at before the warranty expires.
