Normally, Finale draws an element after you drag it. When Update is selected, Finale uses “dynamic drawing” when you drag a handle, letting you see the current position of the element you’re dragging the entire time it’s being dragged. When Update is not selected and you drag a handle to reposition an element, you don’t actually see the attached note (or beam, and so on) moving. Instead, you see thin, dotted-line cross-axes that represent the handle’s position. When you stop dragging, the note (or other element) jumps to its new location.
