Are you sure, that all the clips on the top part, surrounding the screen are snapped in correctly?
I'm not.
But I never unsnapped them.
There IS a visible hump in the left side along the top of the screen, as mentioned above.
Incidentally, the mouse nub doesn't work, really, either....it moves the pointer, but only a fraction of an inch, and it bounces around the top of the screen, over and over...this is just weird.
But Link is supposed to get me an RMA tonight via email, so we'll see what happens then.
