I just installed plotflow on an OSX 10.3 machine and could not configure the appletalk using the PlotFlow OSX application (it's grayed out). So I tried to configure the classic applications of PlotFlow. The Appletalk works but PlotFlow would not allow me to select a mounted volume in the finder to use as the spool folder. I couldn't even see the volume.
The plotflow app is from the Archicad 8.1 CD. Archicad is not installed on the client computer running plotflow. I've had this same arrangement for over 9 years. It works great when the client machine is running from OS9. I wanted, however, to switch to OSX for it's ability to reconnect automatically to the server.
