Object Logo is not screwy because of multiple inheritance.
Object Logo is screwy because it's an instance-based inheritance.

Most o-o languages define classes (types in Object Pascal) of objects with
similar variables, procedures ("behaviors"), etc.  A few languages
make each object unique.  I don't have Object Logo, but Kurt Schmucker 
in his book notes that Object Logo is this way (and he confirmed this
when I talked to him at Macworld about o-o languages in general.)

A good example of multiple inheritance I've heard used is the window.
A window is an object that's part of a list, and it's something visual
(like a QD grafport).  Or maybe you have bitmap objects, and you also
have displayed bitmap objects that inherit both the bitmap stuff and
the property of being in a display list.

Multiple inheritance is pretty rare, mostly for implementation reasons,
so there aren't a lot of good examples out there.
