Do anyones actual LCD screens inside the aluminum housing move around and not sit flush with the front aluminum bezel? I bought mine new, non-refurb, and it seems like there are a few millimeters of space in between the LCD and the aluminum that could allow dust and other particles in. Also, when cleaning the LCD softly with a microfiber cloth, the LCD pushes in a couple millimeters making a creaking sound. Is this normal for 30" Cinema Displays? I'm not sure whether to use my applecare and get a replacement since it's been over 14 days or to just live with it.
