Thanks Malte -- this is pretty much what I tried.  My problem is getting the
thumb correctly sized so, for example, if the field holds 14 items and the
lines number 15, you get a fairly large thumb, instead of the tiny version
when its size is set to 1.  When I try this:

  set the thumbSize of sb myScroll to \
   trunc(endValue of sb myScroll*(height of fld 1/formattedHeight of fld 1))

...the last lines of the field are not accessible.  Guess I'm wondering what
the correct proportion is.
