I have had my 8700c since last November, but I just noticed that in the upper left corner of my screen there appears to be a white "film-like" substance. I also notice a little of the same substance in the lower left corner as well. It kind of resembles glue in a way, as I can see the white substance go across the top part of my screen and then disappear as you move toward the right. It does not appear to be moisture. I was wondering if anyone else had the same problem.
