Ok, I removed the grouping, and tried collision method 1
(MECHSIM_COLLISION_ALL) "Collisions between all
simulation elements are calculated."  The results are
exactly the same as grouping the objects and using
collision method 2 (MECHSIM_COLLISION_GROUP)
"Only collisions between elements of different groups
are calculated."

So, that means that this problem is not a problem with
grouping, but a problem with collision detection and the
way I have my objects connected.

This is too bad, because I really need to connect my
objects that way.
