I was moving a file from a Finder window to my desktop and my screen flashed some weird looking stuff on the screen. I was able to take a screen shot, but is this something I need to be worried about? It never happened on my 2006 Core Duo MB. This is a 2010 13" MBP, btw, 2.4GHz, if that helps any. It's running OS X Lion with everything up to date. It does have AppleCare. Should I take it to Apple?
