On one machine in our office, when the user selects a particular plotter name on the Plot Device tab, the plotter will be set to None, and the selected plotter is now missing from the drop down list. This happens on two of our laser printers that we have configured, but none of the others in the list. It only happens on the one machine, and all the other computers on the network are fine. The pc3 files are shared on the network. The files in the DRV directory are the same as the ones on my machine (which is fine). Any ideas on what might be causing it? AutoCAD 2002 sp1, Win XP. Thanks in advance for your assistance, Danny Polkinhorn WATG Honolulu
