On an iMac5K using Sierra 10.12.8

When working on a separate part In an orchestral score, if you delete the content of a measure, Finale deletes the bar from the score! (Thinking that it's an entire measure stack.) It’s only when you’re working on a single part, having accessed that part through Document” and then “Edit Part”. So if the part is a single stave part, like a flute, and you decide to eliminate the content of one bar using the selection tool and pressing delete, one would assume that it was the content, not the measure itself that was being deleted. Such is not the case, but should be! (What’s happening is that, in a single stave part, the program doesn’t distinguish between a measure that’s had its content selected and someone who selects an entire measure stack in a 30 stave score! ) The solution is obvious - eliminate the possibility of deleting measure stacks in single parts. Leave that for when one is editing the score!
