Hi, I have been very happy with my 11" MBA for these five months I have owned it! However, since the very first time I closed the computer, and then opened it again, I was able to notice a very thin white line going from left to right, and about one third down the screen. This thin white line is not made (out) of dust; it is as if it had been painted onto my screen with a very pointy white crayon. So, I have to clean it every day! Can this be repaired? Thank you, kind regards, igmolinav : ) !!!
