After some trial and error, and reading a few posts and Help, it seems that it is the case that the feature "Chordsheet and Notation - Start a New Line" in the Bar Settings dialog (F5) works as expected (force a new line at the Current Bar) - UNLESS there is a Repeats or Endings (and perhaps other) setting.
Is that the case, or can I force a new line in this manner when a repeat or ending exist? (I found nothing in Help that makes this distinction.)
Thanks
