Hi all, Just today, I suddenly noticed a problem with my iBook screen. When viewed from an angle, there appears to be a smudge or hazy mark down near the middle of the screen to almost the bottom. You can't see it when staring straight at the screen, which I usually am. Someone else was using my iBook briefly today, and I had the opportunity to see the screen from an angle. It's not fingerprints (though it looks somewhat like a very long one), because it doesn't come off and you can't reallly see it from the front. It's easiest to see against a white background, like a Word document, and is uneven down the screen. Any thoughts?
