In the Apple IIgs version of Manhunter: New York (which was recently fixed), whenever I use the MAD, push the INFO button, and input a name, it says 'No one by that name in the city!' no matter what I type in. This includes valid names (like 'Reno Davis'), 'NOTES' or 'BYE'.
I've attached a save game with the MAD open. Just push INFO, and type in RENO DAVIS, NOTES, or BYE to replicate the bug.
