-> select and ctrl-c notes from the 2nd (lower/bass) stave of a piano instrument
-> set cursor to other instrument stave (one-strave instrument)
-> press ctrl-v: this should insert the copied notes, but nothing happens.
Btw, I can copy notes from 2nd stave to first stave of the piano, and then from there copy-paste to other instrument.
Selection including both staves in piano 1 copies without problems to piano 2.
