I have just upgraded from 10.2.8 to 10.4. I run Illustrator 9.0 in Classic mode, pending getting CS2. Now when I double click an Illustrator file it opens in Preview, rather than launching Illustrator as it used to in 10.2.8. I now have to open the files through the Illust.app. which is a pain . . . How can I get it to open Illustrator as before? Andy G.
