I added a new playing technique under “Strings” (to say “slap”). It looks OK attached to the note, and showed up correctly in the side panel until I closed and reopened the file.
Further addendum: Still uncertain of the cause of the bug, but I found an interesting symptom workaround. When I select “new window” I get a screen with all the expressions laid out properly. Then when I closed the original window, it remained OK. See screen shot of the original window and new window side-by-side.
When I close the file and reopen, the problem returns. It seems to affect most of the categories in the right panel… including clefs, key sigs, time sigs, tempos, dynamics, ornaments, and playing techniques.
Do you find that this goes wrong if you open this project by double-clicking it in the Finder, but looks OK if you open it via File > Open from within Dorico?
Yup. That is exactly what it does. Wouldn’t have occurred to me, but now I see that this is precisely what the “new window” approach suggested.
I’ll open it from inside Dorico for now. Thanks for the fast response, Daniel! Wish I could have been in NYC for your talk last week. I missed you by just a couple days.
