After a recent System Software update from Apple, our Optigold Workstations became unable to effectively communicate with the databases from an OSX server. Thinking an upgrade to Filemaker Pro 5 might help, we've done that, but not yet successfully. Filemaker 5 works better, but OG continues to ask for older .USR datafiles when it should really be finding and using .fm or .fp5 files. Any thoughts on what we've been doing wrong? We've installed about 7 times now with no successful result. We're installing on OS9 machine/workstation as OSX will not allow the OG Installer to make any installation -- we figured we'd copy the databases over when all was working correctly -- which it is not locally on the workstation machine.
