Mac os X panther version bug

[richard maxfield]

Help?

Play a version (Version 2, June 1991, Apple date 2003) which came with 
OS X panther (10.3.4)  Updated to 10.3.9.

In the middle of the games, plays by black pawns (the computer 
generated moves) against white pawns are incorrect.  If a white pawn 
moves to the same row as the black pawn( let's say row 5), the computer 
will make a play and capture the white pawn(which is actually on the 
same row 5) and will move the black pawn forward to row 4 right or left 
depending on which column the white pawn occupied.

This happens all across the board, the black pawn moving both to the 
left and the right.
It also happens from row 4 to row 3, and from row 3 to row 2.

Have searched the apple site and gnu site for an update, and can find 
nothing for a mac application.

Any suggestions would be greatly appreciated.
