Hi, I'm new here and I have a question. Why won't my Photoshop 7 work on my new OS 10.5.1?? I've tried several things, and constantly get boxes telling me there's something missing and mentions OS9 a lot.... I even took Leopard off and it works fine, but I can't be switching systems. Do I have to buy a new version of Photoshop, or does anyone know a similar (less expensive) program. Thank you ahead of time.
