I need some help with the following problem:

I have a scrolling field with a list of names of hidden fields. When
the user clicks on one of the names, that field is made visible. 
In addition, I have a button that is moved over the line where the
click was made and then the button's hilite property is set to true.
All this works fine. However, my problem is when the user then scrolls
to see other lines in the field. As soon as the user starts to scroll,
I would like my button to become unhilited so as not to distract from
the scrolling field and ruin the visual effect. I suspect I could do
this by overlaying my own buttons on top of the scroll bar to simulate
the scrolling, but I am hoping that there might be a quicker and
easier solution. What I would really like is something like

on clicking in the scroll bar
	set hilite of btn x to false
	start the normal scrolling behavior
end clicking in the scroll bar

Any suggestions?
