...background copy flips too.? I just recently upgraded to a mac and added CS4. I've never had issues on my pc with flipping images. But now on my mac when I go to flip my layer copy of the image to do a mirrored image, it flips both the original background and the copy. I have tried everything that I can think of to fix this problem. I've even uninstalled and reinstalled the program. It's very frustrating! HELP.
