Werner,

I"m not really surprised that having a MovingObject inside a
MovingObjectGroup doesn't work quite right.

I suspect that some extra code will need to be added when making a
MovingGroup. i.e. something that adjust the positions of all the
sub-objects at the end of the move.

I"m still a bit confused about how this is all nested. If you could
make a stand alone sample with a couple MovingObjects in a
MovingObjectGroup, that may clarify it, and help one of us figure out
where the issue is.
