We have just upgraded to V12, and are having a really annoying problem. Any time we open a drawing, and at various other times (I think auto-save does it) I get a spinning color wheel and a message:
CONNECTION FAILED
The server may not exist or is not operational at this time. Check the server name or IP address and try again.
If this happens while i am in another program or drawing and not aware to click OK, the drawing that the error came up on is completely frozen and i have to force quit and re open it. We are running two MAC G5 PPC's, connected through apple talk. We are not on the main server for the office, which runs PC's.
Thanks for the info. Via Google I wound up at the Apple site and downloaded a free utility called PListEdit Pro and used that to turn "on" DisableCrossPlatformMountingFeatures.
Seems to work fine now and needless to say, loading files in AC 12 is still on the slow side, but much, much faster.
