We moved both the image files and the Quark files to the Windows server. If you open the Quark file, the user is informed that the links are missing. We have even created new Quark files and linked them with existing image files and the same thing happens. It initially appears ok and the links are there and valid. But once you close the file, wait a little bit, reopen the file, the links are missing again. Permissions on the server are wide open. The user has permission (full control) to both the Quark file directory and the image file directory.
