I have found an unusual quirk when resurrecting some unfinished NWC files of some years back.
These files have two staffs each for both the "right hand" and "left hand" parts, but when "layer with next staff"is selected, although the check mark shows as a tick, nothing happens. The two staffs remain steadfastly independent.
This does not particularly concern me as I am rewriting most of the material, but I do wonder why it happens.

Hi, Tony.
You need to tick the "layer" box in two different places - both in the Staff Properties (Staff|Properties|Visual) and in the Page Setup (File|Contents).
Perhaps you left one unticked?

John,
You are so right! Normally I always tick the Page Set up box, but I did not in these cases. They are very old files, perhaps I did not know how in those days.
