Just saw something in Dorico Pro 4.3 I do not recall seeing before.
I have been copying lyrics from my text doc, running through Juicio Brennan for hyphenation, and then pasting them onto notes via the Lyric Tool as I have in the past.
In this case I alternate between characters, clicking on a note and pressing SHIFT+L before continuing to paste the lyric. From the diagram, one can see the first word/syllable attaches to the bar line instead of the eighth note selected before invoking the Lyric Tool. For some reason, it only affects the upper staff.
Of course I can move the syllable back manually, but I wanted to point out this unexpected situation.
It seems as if closing and re-opening the program may correct this. Still, puzzling.
