Apparently I have inadvertently pressed a key or something that has changed
the way my scrollbars operate. It used to be a "live scroll" rather than a
"jump scroll". In other words, the page used to scroll as I dragged the
scrollbar. Now it just displays that useless little tooltip showing the row
or column to jump to when I release it. Is there a way to revert to the
alternate method of scrolling?

TIA,
Charlie
