Oh, oops, just discovered an oddity while playing with the grouped 
stick figure.  If I
grab the *end* of a NCConnector, and separate it from the circle it 
was attached to, I can't reattach it because it flies off to 
somewhere outside the group.  At a guess, the attachment is in some 
coordinate system very different from what it needs to be to stay 
near where it was before.  This isn't a problem with Connectors, I 
would guess, but may be Group behavior that has to be modified if I 
want to be able to treat a group as if it were a composite figure in 
a PasteupMorph.

Any suggestions on this one before I dive into debugging?
