I added that.

self is a ScorePlayer. Not a ScorePlayerMorph (which is what I'd have expected
given that I'm defining the method in that class) or a button (which I
understand not to expect). So I examine the rest of the code in makeControls
and I find that wherever it sets the target to self, the actionSelector is set
to a method defined in ScorePlayer rather than in ScorePlayerMorph.

So what I'm missing -- at the very least -- is the connection between
ScorePlayer and the ScorePlayerMorph. Why would a method defined in SPM (tired
of typing the full name) have a "self" that refers, not to the SPM but to the
SP? That just doesn't make sense to me, particularly when the two classes are
in completely different hierarchies.

I'm now officially more confused than before, but I aprpeciate your patience,
Randal and Bijan.
