	However, you are still screwed if you are dealing with gadgets that
have only GadgetText linked to them.  This is probably due to the sequence
in which Intuition renders the Gadget imagery.

	The reason this approach works with Image gadgets is because Images
are rather like bitmaps, and thus blitz over the previous imagery
(highlighted or not).

	However, the use of an Image in a Gadget deprives you of the
ability to put a Border around your gadget, unless you make it part of the
image.

	This is *too* a bug (my opinion, my opinion).  The fact that it has
existed forever doesn't make it any less irritating.

	Too bad the Gadget's MutualExclude field is still unused; this
problem wouldn't exist otherwise.  Sigh.
