I can't get crafty to ever think about Qf7 for black here... It only
considers fxg5.
Bd7 22. Bf2
11 4.20 -4.42 16. ... fxg5 17. Qxg5 Qxg5 18. Rxg5
Be7 19. Rg2 Bd7 20. Rgf2 Ra6 21. Kg2

22. Rh6 Rxf5 23. Kh2 Kf7 24. Rh7
Any idea what is going wrong here???

I am not quite following this. This game was played by you against another
program (not crafty)? I don't see how crafty could improve on it if it has to
follow the game in analysis mode, since it can disagree, but it still is forced
to follow the moves played in the game. IE the Qf7 move I can't get it to play
under any conditions... black was totally won at that point.
