Thanks fellas for the advice.
I am skimming through the DipTrace tutorial and Help system to try and get a handle on this program. Although my career was in programming, I'm more familiar with compilers and databases than with running mouse driven programs. I'll get it eventually.
I'm using the freeware version as I think that will be adequate for my intended design work.
I'm going to have to read through the beginning of this thread again to find out how we arrived at this point in our discussion. Maybe I should start a new topic; Help with DipTrace. I'm sure I'm going to need more advice.
