"Score pathname" in "Score properties" not updated on "Save As..."
Saving a file to a different pathname does not update the pathname as reported in "Score Properties". There is debate about whether the current behavior (displaying pathname it was loaded from) is more useful. While many people feel that "current pathname" is something that changes when a Save As is successfully performed, and full file pathname is a very fundamental attribute of a file, others feel that in recent years, it has declined in visibility and importance in modern UX's. See the (first) linked page for such debate.
