Try using the "cachSelcVPos" and "cachSelHPos" fields in the Text Edit
record.  They tell you the last vertical and horizontal position at
which TE drew your insertion point. -- If that position is outside your
window's portRect (at some point between StartDrawing and SetOrigin(0,0),
when your window's port's origin reflects the scroll bar settings), then
you need to scroll your stuff, using SetContentOrigin on your window
(not using TEScroll).

There is no conflict with using multiple fonts in your TE control and
also using TaskMaster.
