Sarah,

You are quite right. Returning to the stack I found that the substack 
does get the focus. Don't know why it didn't do this earlier.

Jacqueline,
I stumbled on an even simpler solution.

on mouseLeave
    if the mouseLoc is not within the rect of me then set the points 
of graphic "arrow" to ""
end mouseLeave

This would appear at first to be redundant. That is, if there is a 
mouseLeave message, the mouse would not be with the rectangle. But, 
as you pointed out, it can be in the rect and yet leave when the 
arrow graphic is created at the mouseLoc.  Apparently, however, it 
(the engine) still thinks the mouse is within the field rectangle.

So this handler has the desired effect: It sets the graphic points to 
empty only when the mouse actually leaves the field rectangle.

Sannyasin,

Thanks, that is all I needed to know to get started. I had assumed 
that this was all done within RR.
