Piano Roll Behavior

When changing the pitch of a note with midi input via the piano roll, if the note to be edited is out of screen (2 octaves up or down) the piano roll jumps with the screen thus changing the note my mouse is on. This then causes multiple notes to be changed because with the piano roll moving, I am in effect, sweeping the mouse across the piano roll. Could the behavior be changed so when I click once on a key, Cubase registers that as one note to be edited?.
