Sorry if this has already been covered, but after the scrollbar is
removed the toolkit should mark the area under the toolkit as needing
redrawn. That will then cause [EmacsView drawRect:], and subsequently
expose_frame, to be called on that rectangle. Why aren’t the cursors
being redrawn at that time?

Is everything else ‘under’ the scrollbars being drawn correctly?
