After installing Leopard, Photoshop 7 isn't working. Now, I have searched around and found that few Adobe Photoshop products work. I'm planning on buying a newer version -- however, I would like to ask, which Photoshop would be the best in this case? Which one is more compatible -- CS, CS2 or CS3? I'd hate to go out and buy a version, only to find out it doesn't work. Thanks in advance.
