I am trying to print the parts, but in Print mode, I can only see the full score. In the layout selector menu at the top I do see the part name, but that part isn’t showing in the score below. Also, I cannot make a choice from this menu, it cannot be selected, it appears to be locked:
Andre, look to the list on the left in Print Mode.
Select there, what you like to have printed.
aaaahhhh… thanks! 
“Parts printing not possible?”

it’s a matter of habit, in the rest of the program you switch to other layouts with the top window menu.
I didn’t mind helping
