There are some incompatibilities with the datatypes Multiview uses between versions 3.0 and 3.1 of the OS if I recall correctly. I'd use a v3.0 Workbench until you replace the ROMs if I were you. Or maybe just copy the datatypes and related libraries from the v3.0 Workbench disk over the 3.1 install, I haven't experimented with that but I suppose it could be worth a shot?
