Anyone else having this problem? I have a skin from bestskinsever (similar to Zagg) on my iPad, just to protect it from scratches and I also the Apple Case on it. I just took my iPad out to clean the edges cause lots of gunk was getting in there, and on the back of my iPad was blue imprints from the Apple Case! WTF!? Anyone else using the same/similar combo and getting the same result as me?
