When I deleted 20 bars’ worth of simple piano music from this project, with Insert mode on, Dorico became unresponsive for a long time (maybe 10 minutes). The cursor turned into the wristwatch icon, which I have been seeing quite a lot of recently. Nothing happened except that at one point all the bar numbers disappeared. Eventually I decided to create a diagnostics report. This also took a long time (at least 20 minutes, I think), but once it was done the project had become usable again. Is this normal?
The VST I was using was again Synthogy Ivory II, but this time it is the latest version, and anyway playback was stopped when this happened.
