PokerTracker

Mac OSX + PT 4.17.8
On Winamax the hud is displayed correctly but the stat update does not work.
Fir instance a player has 40 hands played at the table but my hud dispays only 14 hands.

Presuambly you are getting the number of 40 hands for this player from your PokerTracker 4 reports? Make sure you are not using any HUD filters that would reduce the number of hands you are seeing for this player in your HUD:
