    Running: iMac - OS X 10.5.4

    I have these boxes at the top of my screen that just started to appear. I think they started to appear the same time I did a recent Software Update -- I may be wrong on that.

    I've tried restarting my computer a few times, help there. When the top of my screen is black (ie. full screen DVD playing and the top .5 inch of the screen is blacked out) the boxes that appear are red instead of blue.

    Also, they appear in screen shots? So I'm guessing it's not a stuck pixel. When I zoom-in the screen (ctrl + wheel-up) the boxes flicker on and off...another reason I don't think it's a stuck pixel.

    Also, they only appear in the top portion of my screen, no where else.

    Any clues??
