I have the 2010 13" in my sig, and i have noticed lately it is getting a lot of lag on the screen while scrolling. While watching any streaming video, the sound will continue, but the video will freeze for about 2 seconds, and then resume playing. It does this a LOT during videos. And the while scrolling through a webpage or up and down in itunes, it will freeze for about 2 seconds, then scroll up or down wherever i choose. I noticed this within the last couple of weeks, and a reboot will help fix it, but only temporary. It starts after only a day or two of being on. Im one that doesnt like to reboot my computer every day. This thing has gone weeks without ever needing one, so it is a bit of a pain and frustrating that it wont 'keep up'. Its not that old at all, i got it in about August/September Any ideas on what it could be?
