One can get small combination locks where instead of a padlock hasp there is an extendable, vinyl-covered steel cable which one can snake through handles, loops, or whatever of the items on a cart like that. Including at least one with a loud alarm if the cable is cut or jerked. Like Targus? or Defcon? or maybe Kensington? has had them. Mentioning which does not lessen my own sympathy for your plight. :-( On Thu, 11 Sep 2003, Dr. Trevor J.
