my layers keep breaking up into bits. i'm just working in cs6 and all of a sudden half of my files have square looking gaps where info doesn't appear to exist, although they should be whole, and my text keeps turning black. when i edit it, it goes back to its actual colour, but upon clicking submit it's broken again. i've tried restarting, nothing seems to work this time around (it happened before, i restarted and the layers were ok upon dragging each of them. the pixels suddenly appeared). help..?
