Try getting the scrollTop of the member on frame updates, and setting
the shape's location based on that. Oh, wait -- custom scroll behavior,
so I guess you're not using the built-in scrollbars. Well, that
behavior obviously knows about positioning, so it should be able to
send the information out when you poll it -- I mean, you might have to
write a handler for it that allows you to get its vertical scroll
value, but that should allow you to get what you need.
Have you looked at keywords such as 'selection' and 'selectedText'?
Offhand I don't know if they work to hilite parts of non-editable
members, but if so, that might take care of your problem too.
