I have analysed several matches at 4-ply using the 20091002 Windows build. I am 
finding the move made in the game record often being changed from that actually 
played in the match to what GNU thought best - which obviosly then renders the 
rest of the game meaningless garbage full of illegal moves.

Example:

My opponent moved 8/2* 6/2 which is correctly highlighted in red. The problem 
is that GNU puts its preferred 24/18 22/18 into the game record in place of 
8/2* 6/2 - thus rendering all further analysis of that game meaningless.
This nonsense seems to have affected almost all the games I have analysed.
