We seem to have one of the most annoying problems w/ our plotting to our 1050C. Half of our computers in our office have WinXP, the other half Win2000. Whenever someone in the office w/ WinXP tries to plot a drawing using a page setup created by someone w/ Win2000 we get an error dialog "Unexpected Null Pointer", and the pc3 file for XP disappears. This happens in the reverse too, and also creates problems w/ batch plotting, etc etc. I think this is a driver problem, but any suggestions of how to get all to be able to share page setups and pc3 files throughout the network w/ these two operating systems in place? Thanks. Jeff Curtis
