For the developers,

Dorico just crashed while working on a project. I had clicked on the comma breath mark in order to load the mouse when the crash occurred. The Crash Diagnostics file is attached.

I’m sorry that Dorico crashed for you. I’ve taken a look at the crash log and I can see that the program did indeed crash when processing the command generated by clicking the button in the panel. Unfortunately I don’t think it will tell us enough to allow us to find a problem and prevent it from happening again in future. If you do manage to come up with a set of steps to reproduce the problem, please let us know.
