Hi, I just got a MacBook Pro Retina "13 two and a half weeks ago (so happy. It's a great laptop!). Just a few hours ago I saw a white pixel in the middle of the screen that seemed to show up at the very moment I looked away from my screen. I closed the screen and opened it up/logged back in, and it went away. It came back just now, but in the process of registering for this site, it went away again. It's really distracting and irritating, and it's only happened twice! Has this happened to you? Any suggestions? Thanks!
