It was something about "overlay-scroll" or whatever. need help tho

[Gary Kline <kline thought org>]

it took me the entire afternooon to get an idea of what those red
thin linnes a "thumb" bar were.  i think it was only in ubuntu...
and i have fixed parts of it.

now i have two separate horizontal scrollbars. they range from 0 to
100 exactly what i want.  and now, in place of that red line is a
regular groove with a tab inside that you slide to and fro.

my quandry is how to move the first grove up beneath the first
scollbar with a "0"?  do i need another box--a box4?  i have tried a
number of things, but nothing works.  can anybody help me?

thanks in advance,

gary

code appended below my sig.
