Just a follow up! I downloaded and used Version 2.13 and am very pleased to report that I had NO issues and NO crashes (although I still save every time I do a change – just a habit). The new automatic backup is a nice feature but I couldn’t quite ascertain when it backs up the file, is it after so many minutes or just when one actually saves the file? Anyway, the program is starting to feel much more robust. I will keep you informed if anything else evolves as we go forward.
