have you tried doing 'clear all nets'?
then using the old fashioned 'make netlist' 'load netlist' instead of
the 'update pcb'
this may show the source of the trouble, esp if you inspect the netlist

Again, thank you for your suggestions, Peter and Brad. Things are not looking
good. The relay footprint is a circular pattern, and it's centered around the
(0,0) origin. I have a much earlier PCB, before I entered the many changes,
that has the relays on the board, along with several other components that I
now realize are missing in the new PCB. I made a copy of it and tried to update
it, but the changes were so many (renamed components, etc.), that it ended up
with macros that it would not complete. It could no longer get to the new from
the old.
I believe that I'm dealing with some type of file corruption now, but I can't
put my finger on exactly what it is. I noticed yesterday that I had lost the
power and ground plane assignment to the PCB, and there were no nets available
in the dropdown to select from. Big flag on the play, there. A computer
restart
fixed that, but nothing else.
From the PCB, I generated a footprint library and it has all the footprints
(including the ones that are not visible on the PCB). I'm thinking about moving
my files to another computer and see if the problem follows, using that to
isolate between problems with the Protel application itself and my DDB files.
Thanks again, Michael
