     Hmm, that's not bad.  It doesn't give the effect I was trying to
describe, however.  I consider the "active" editText item to be that
item with the insertion point or active selection range in it.  The
idea is to use the iBeamCursor only when the cursor is over this item,
and not over other, non-selected editText items.  Before anyone
accuses me of using a strange User Interface technique, let me say
that the effect I am suggesting is also used by the MPW Commando tool,
although I don't know what method Commando uses.

     (*DialogPeek->textH)->viewRect gives you the Rect enclosing the
active editText item, which is what I need for my cursor changing
algorithm to work.  I don't suppose you could find that without using
DialogPeek?
