I've just been working on a Photoshop 7.0 file on my Powerbook. I've just saved the file and although I physically saved it as a jpeg, in the finder the file is now a .ivc file with an icon that looks like some sort of document icon with a belt being pulled tight around it (that's going to mean nothing, probably). I can't open it in anything. What's happened? Using 9.1, on a Powerbook G4 with 192Mb and lots of hard disk space.
