Oops, I solved the wrong problem in the last message. The problem is not
highlighting the field, but un-highlighting when you scroll. I would put
a button over the scrollbar. The button should be hidden, until the field
script is executed,. i.e.,  inside the field script should be:
   set visible of button "scrollbut" to true
Then, the button script should deselect the line in the field, and hide
itself:
 on mousedown  --note, this is a mousedown, not mouseup handler
   select char 2 to 1 of cd field "scrollfield" --unselect line
   set visible of me to false              --hide me
 end mousedown
