v1.4.0 decides draw but game was won #848
Description
In a 5m+3s game between 'Alice' and 'MicroMax', both XBoard engines, CuteChess GUI v1.4.0 decided a draw while White resigned - but the engine gave 1/2-1/2 !?
It's a weird case, CuteChess indeed decided a draw, see the window title :
Alice was incorrectly 'claiming' a draw while resigning, why did CuteChess 'accept' a draw ?
Here's the log tail in text format :

Note: i put "OSP", meaning "Only Starting Position", but i was wrong : Alice CAN start playing from a certain FEN.
