I upgraded to the newest Finale.
I reported this bug a year ago.
Apparently it has been around for a LONG time.
It is still there - you cannot copy and paste a measure with a staff style in a part, only in the score (and then it does not appear in the part)
This is a BIG pain in the ass especially when it comes to Drum Set parts:(
Any plans to fix?
