Quite a leap, I'll admit! But I have, perhaps stupidly, been using PS7 for many years and have only recently felt the need to upgrade. I use the software to create digital art, collage and painting with a Wacom Intuos 4, and save the majority of my work in PSD and JPEG. Will I experience issues upgrading to CS6 if I want to open my files which were created in PS7? They open and function just fine in the Photoshop Elements which I have installed on my macbook pro for web use. I am a bit scared of this upgrade for obvious reasons, and would prefer to purchase CS5 (for mac/UK) but can't seem to find it for sale. (Don't wish to use creative cloud, for I only work with PS). Any advice?
