Files on our network are duplicating themselves, not only once but multiple times. When I click on the original file, a QuarkXPress 6.5 file (we have also had this happen with Indesign CS3) the file duplicates, then opens in the native program. Our network (server) is Windows based, just switched to Leopard 10.5.6 and we are running AdmitMac v4.0. This problem started when we began using our new Leopard systems. Any advice? Thanks.
