Reliable script to handle selection/drag-and-drop in a list field?

It's great Geoff!   The one minor issue I noticed is, after a drag/drop
action, the field doesn't appear to be put back into a state of being able
to drag a new line.  Doing so seems to enable one or multiple line
selections, but no drag.  I have to click a second time to start a drag
action.  But otherwise seems to work as expected.

No "take down" necessary.  If anything, I would ask if I could add a copy
to my site, so folks have more places to find it.
