Guy,
I understand my suggestion didn't fix your problem, but as to your point (A),
that setting visiblity to False should hide objects and not delete them,
from the VPython Docs:

Deleting an Object
To delete a Visual object just make it invisible: ball.visible = 0


(Not that I agree with the behavior, I'd prefer being able to make
things visible and invisible
at will without having to manage the invisible objects (i.e. deleted) myself)
