I have searched for this and couldn't find anything. My wife is having a problem where she uses Photoshop CS2 on an eMac at school and a windows PC with Photoshop CS2 at home. The problem is that files saved to a USB drive by the eMac are unreadable by the PC. However the eMac can read CS2 files saved by the PC. Other files(word, excel, jpegs, etc). Is this a common problem or is there some setting I need to change to make this work?
