Was your passenger in the front or rear? AFAIK, the window lock only disables the rear controls. A front passenger can still operate their window, and the driver can still operate the rear windows even when they rear controls are locked-out.
Re-circulation should only be used temporarily. It's a safety feature that it disables when restarting the car. I only enable re-circ if I'm driving through an area that I know will stink (like North of the grapevine on I-5, oh many those cows, yuck!) Otherwise, you WANT fresh air to come into the cabin.
