I promised some of you that I would test CS1 in the new Leopard install and I'm glad to report that (so far) it seems to work fine. Impressive on both Adobe, and Apple's part in my book, given CS1's age. I haven't crunched any huge files yet, but everything I grazed over seemed to be in working order. (I'm only talking about Photoshop and Illustrator here, by the way). You might note that I had CS1 installed on my hard drive and did an “upgrade” to Leopard. I didn't install CS1 afterwards. Check out the screenshots:

The font drop down is really wide.
Even the beefiest filters seemed to work ok.
