I currently have CS version 1. All I use is Illustrator and Photoshop and by no means do I ever push the envelope of what they can do. I'm actually happy with this version of photoshop but Illustrator takes my Win7 out of Aero which is annoying. It also has some intermittent display issues. Anyway, my copy of CS is too old to qualify for upgrade pricing and I really don't need, or can really afford, the latest. Where can I get a legal, older copy of CS that works well with Win7?
If I see something on ebay, what do I need to look for to ensure the license will be valid?
