Is it normal for the bottom right and left hand corners of the plastic casing surrounding the screen to be slightly raised. I can only notice this when I'm looking downwards on top of the screen as I'm closing it, and I can gently press the bottom left and right hand corners of the casing against the screen (I'd say maybe only one inch on both the both the bottom and side of each bottom corner is slightly raised, the rest of the length of the case sits seamlessly against the screen itself. Does this make sense? Is it normal or do none of you have this problem? The gaps are minor, and do not affect the screen display.. but it does certainly seem odd
