I recently upgraded from 4 to 5, and all seems to be fine, except that when I close a project, Dorico quits and it asks if I want to send a message to Steinberg. Then when I go to restart, it asks me again. And I have to ‘Recover Selected Project’ before I can do any more work.
There’s a known bug that was introduced in the latest minor update where if you have anything selected (like a note or whatnot) at the moment you close the project, it will crash. if this is the issue, it should close properly if you don’t have anything selected when you close the project.
