Hello everyone...I got a MacBook Pro a few months ago. I noticed recently that in the middle of the screen - whenever I have a dark background or watching a movie w/ a dark scene...I see what I initially thought was a smudge or streak. However, I tried to rub it with a small cloth thinking that it was dirty. However, it's not dirt or a smudge. This think is really annoying because anytime I view anything w/ a dark color I can make out this whiteish shadowy thing... Any thoughts as to what this might be...? I'm planning to bring it into the Apple Store this week.
