Jacqueline,

I never would have guess this resolution. Knowing what the problem is 
I can work around it. The following is clumsy but it works:

on mouseLeave
   put 2 into tMargin
   put the mouseV into tY
   put the mouseH  into tX
   if tX - tMargin < item 1 of the rect of me or tY - tMargin < item 2 
of the rect of me then
     set the points of graphic "arrow" to ""
   end if
   if tX + tMargin > item 3 of the rect of me or tY + tMargin > item 4 
of the rect of me then
     set the points of graphic "arrow" to ""
   end if
end mouseLeave

I can't just use "if the mouseLoc is not within the rect of me" since 
it is within the rect just before it leaves.

Thanks much,

Jim
