Castling bug in gnuchess version 6.2.5

[Raul Granados Barbero]

Good evening (writing from Europe), 

It happens that when trying to input a castling move as o-o the programme reports it as an invalid move, although it shows in the figure as if the castling was already made. Any input after that error is considered invalid, making impossible to continue the game. Please see enclosed figure. It also happens with the graphic option disabled.

Thanks very much for your help.

Regards,

Raúl!
