Yes. It is a fussy trivial bug the fix to which is
MorphicEvent>>cursorPoint
^ self subclassRespnsibility. 

My curiosity remains. Are there other places where
abstract classes or not-so-abstract classes use words
they should know but don't.  A test will settle the
question and guard against future sloppiness.

Even if squeak has no other instances or only trivial
other instances another test of correctness is a good
thing to have.

And enumerating the messages to self may have other
useful purposes we haven't thought of yet.

So the question:

For a given class how do I enumerate all the messages
sent to self? 

Is something I could use a clear concise answer to, 
from someone who may know exactly how to  say this to
squeak in a way it would understand.

Motives and examples are sideways to the curiosity and
the point. Its a newbie question and I'm not ashamed
of my stumbiling around. That's how newbies learn.

Yours in curiosity and service --Jerome Peace
