There are only two reasons that The King engine would be running immediately
after entering the Game Room for the first time:

1) The Visual Thinking window is open. This starts a mentor engine, just like
checking the "Chessmaster" checkbox in the Thinking Lines window (although, if
BOTH the checkbox and the Visual Thinking window are open, they use the same
instance of the mentor engine).

2) One of the players in the game that was in the Game Room when you last quit
Chessmaster was a computer player. Chessmaster saves the players in each room
upon exiting, and they are restored when you start up Chessmaster again. If one
of those players is a computer player (Chessmaster personality or imported
engine), then its corresponding engine is automatically started up, ready to
play the game.
