I purchase Mac OSX 10.5 (Leopard) when it first came out but was told to not install it by our Mac computer administrator at work. When I asked later, I was told that it still have problems with the Adobe products. Are some of you using Leopard with Adobe CS3? Is it working for you? I would really like to switch my group over to the new system, but since Adobe CS3 is the main software that we use, I can't risk it if there is still a problem.
