Violins 2 and Viole are loaded as Section Players. The icon in Setup is two heads+.
When I Right click > Staff> Change Divisi and add a second staff I get the following alert:
“The selected instrument is held by a solo player. You can only create a divisi change for an instrument held by a section player.”
And yet it is a section player.
But that is only if I have just played the music (opt-P). If I do any other action first, the pull down menu containing “Change Divisi…” is greyed out.
Opt-P and the menu is back again but followed by the above alert.
