// GK1 english pc floppy locks up on day 10 in the honfour (room 800) when
// using the keycard on an unlocked door's keypad. This is due to mistakenly
// calling handsOff instead of handsOn. Sierra fixed this in floppy patch 1.0a
// and all other versions.
//
// We fix this by changing handsOff to handsOn and passing 0 as the caller
// to gkMessager:say since the script disposes itself.
//
// Applies to: English PC Floppy only
// Responsible method: sUnlockDoor:changeState(2)
