The practical problem I notice is at
http://mindprod.com/applet/vercheck.html

Vercheck displays a scrollable table.  You can ask it to update each
row of the table by probing the corresponding web site in turn.  As it
goes it scrolls the table to keep the item it is working on in view.

However, sometimes you want to override this behaviour to take a look
at something off screen.  You scroll, but the program immediately
yanks you away.  I would like it to suppress programmatic scrolling
for X seconds since if you scrolled, presumably you are looking at
something and don't want it scrolled offscreen.

This desired behaviour is something I think JScrollPane should always
do, not just in Vercheck.

It is a lot easier to combine things later that 
have been too finely categorised than to split 
things later whose are categories are too coarse.
