OK DO-KEE, I'm going away for a few days later this morning and will probably be incomunacado, so thought I'd summarise score problem a bit more succinctly.
As far as I can see, when a player wins, the stake is being added to the score as well as the actual winnings.
Yes, you get your stake back so it does not come off your score as for a loser, but neither should it be added to your score.
