It makes it happen, but then if I unlock the spin buttons (uncheck the
lock check button), then how do I make them work independently? Wouldn't
the two spin buttons have to have different Adjustements then?

Also, I'm building this in glade, which doesn't let me use a common
Adjustment, but that's a different story.
