Peter, Gravenstein,
Thanks for your advice. I did read your article on Opening
Projects , Peter, and after deleting the .cpd and the
rhvariable.apj (which was indeed 0 KB), I have been able to open
the project with no error messages, update topics with images and
build tags, and check-in updated topics to RoboSource Control
without incident. My .cpd is now 2.5 MB, which seems reasonable.
I haven't tried deleting the .xpj file yet, but if I get any
more error messages, I'll try that.
I'll leave this thread unanswered for now, and see how it
goes for a couple of days.
Thanks,
Dan
