Yeah, I'm already including a minimum scrollbar thickness of 5 pixels as
part of my Morphic ScrollBar changes, since I noticed the same problem.  5
seems to be thick enough to grab easily, but thin enough to show that
you're looking at a tiny fraction of the entire list/text.

(Actually, I'm not sure if you were referring to the MVC or the Morphic
scrollbar... I guess the dissappearing problem can happen with both.  It's
not as big a deal with the MVC scrollbar, though, since you don't need to
"grab" it in order to position it.  Still, it might not be a bad idea to
have a tiny minimum thickness for the MVC scrollbar as well, so you can
at least see where it is.)
