But only in photoshop. I can drag a file onto the dock icon and it will open photoshop but it won't open the file. Same with double clicking, it will open photoshop but not the file. Other Adobe apps will open OK, I can drag a jpg to Illustrator and it will open fine. I've checked it against a virgin account and it is the same. How can I restore normal behaviour. I've done all the permission repairs and maintainence tasks.
