I'm having some problems using multiple proportional gadgets in one window.
The following things are happening:
  1.  The gadgets seem to require one click to "activate" them before trying
        to switch from one gadget to another.
  2.  The gadgets tend to leave pieces of their knob behind when clicking
        to either side of the knob (but not on it).
  3.  Frequently when klicking on either side of the knob, the gadget will
        move 1 step in the other direction, and then function as expected.

Well, I guess that's about it... If anyone has any ideas about what the
problem, I would greatly appreciate it.  I could mail out the source code,
if necessary, but it is pretty messy (this is my first attempt at C
programming).

Thanks!
