While I was listening a piece I decided to move a staff upward.
The playing was still perfect.
The note catching... funny!
Nothing really serious.
After a stop and go everything was ok, but perhaps it can be a good idea to lock such commands while NWC is playing.
Thanks for the report. It actually has the potential to be serious, as it causes significant confusion in the NWC2 internals.
Is the solution to prevent moving staffs up or down during playback?
Correct.
