Hi Hilaire,

The problem is that ChevronMorph inherits from PluggableButtonMorph. But 
PluggableButtonMorph is a kind of Widget. From the Widget class comment:

"Hierarchy for morphs that are rectangle like, and that occupy an area 
that can be specified as a Rectangle. This means that, besides being of 
rectangular shape, sides are aligned with local coordinate axes. 
Including rectangles with rounded corners and such. The idea is that the 
'extent' ivar is all that's needed to establish our dimensions and shape."

ChevronMorph is not at all like that. Adding back methods from Morph 
that were redefined in Widget (see attach) it starts to work better. But 
I think a better way is to subclass MovableMorph, and maybe copy any 
instance variables and methods from PluggableButtonMorph that might be 
needed.

Maybe we'd rename Widget to make all this clearer. Or find some way to 
make it clear that it is a hierarchy of boring little squares, and 
nothing more.

Hope this helps.
