I am digging a deeper hole for myself by the hour I think. Trying to make a blank notehead set, I followed in detail the instructions in various threads here, as carefully as possibly. I can make a blank notehead with text spaces. But now, I can only change noteheads in Engrave mode and although the function is not greyed out in Write mode it does nothing, with any notehead set, and worse, the rubbish bin icon in the Notehead Set dialog is greyed out and I cant delete anything, for any notehead set.
I am at a loss to know how I could have corrupted things this badly. What to do?
I have become more and more convinced that the feature request to hide noteheads is something very much needed, if you can mess things up this badly by having to use workaounds.
Is it time to reinstall Dorico, in this case?
