Correct. As my book tells you, "The rule seems to be that sending a message to
an appearance proxy will affect _future_ instances of that class, but it won't
spontaneously alter the look of an object that is _currently visible_ in the
interface. The look of an existing object will be changed, however, if that
object is refreshed somehow." I suspect (as the book goes on to say) that using
UIAppearance to change the look of an existing widget is a misuse. You want to
change the way an existing widget looks, just change it. m.
