In the attached file I have copied 2 bars of a piece for choir and organ. I have copied notes from the choir into the organ part and now I can’t lengthen the slur in the first bar here. Neither with Shift-Alt-arrow right nor with the mouse.
If I delete all and input the same again it works. So something must have happened during the copying process I assume.
Maybe helpful for the programmers to find out what it is in oder to prevent such situations in future.
