Not shure what you mean, works for me.

Too much activity on the peripheral visuals for my taste.

If you change the start position then you constantly need
to watch it whether it's still there where you left it off.

You mean subclass the control? Shure, why not.
If only there wasn't one more general problem which Xaw
(if thats what I figure) does not have because it doesn't
have a slider, really. That is with a slider if you can
grab it at the lower end, it means you end up pulling
below the frame bottom and outside the monitor if the
slider gets shorter during dragging. So ...
