One thing I've forgotten to mention in my previous replies is that it's really unfair to compare the performance of an editor (MBC) with a viewer (LDView), even if both are running on the same machine. A viewer doesn't have to worry about adding, (...) (22 years ago, 17-May-04, to lugnet.cad.dev.mac)
