Dorico crashing on deleting double bar lines

I have had Dorico crash 4 times in the last 30 minutes. I am trying to remove some unwanted double bar lines and I can remove one (either by clicking the single bar or by pressing Del) but on the next one the program crashes. This is a very large file (14 Meg) if that might have any relevance.

Have you tried any smaller files? I just tried adding and deleting some double bar lines in a piano piece, then a short orchestra piece, with no crashes. It did take a little longer to delete them in the orchestra piece, which is 519 Kb.

It seems fixed now. Apparently it was just deleting and not using the bar line tool kit.

If you have any crash dumps/logs, Bob, it would be helpful for us to see them. Please email them to me at d dot spreadbury at steinberg dot de if you can find any.
