Problem extending barline
I'm having trouble extending a barline. This is a barline I added from the palette to show the 3+2 division of the 5/4. After I extend it to the end of the lower staff using the hook, if I click anywhere it disappears. I does not happen every time. Some of them reach the bottom of the lower staff and they stay there, but others not (In the attached score it worked on m. 1-3 but not in m. 4). What may I be doing wrong?
