I received my K2 on Friday and am starting to learn my way around - it is great and I just bought my first book (Team of Rivals). I certainly have a lot to figure out, but I do have a question. I can sometimes see the shadows of the prior page when I move to the next page. I've noticed it the most with the screensavers, when I turn the Kindle on. Is this normal? (I hope so - I don't want to return it!) Any thoughts would be appreciated! Ellen
