I got this message when trying to open an indesign document: "cannot open document" "May not have permission".We have a small network setup, 3 Mac G5's and 2 Mac G4's. Our main G5 has a 2 external drives where we archive documents. When I tried to open an indesign document that was saved in the external drive from a computer other than the main G5 I get this error message. I can copy the file to the desktop and open it but can't open the original in the external drive to modify it. Any ideas? Thanks!
