I have had no problems with this fun program ... and am puzzled why there haven't been more downloads and players on line at a given time ...
It's a pretty fun game -- and if you don't have a bully in the room with a fat bankroll who tries to buy every pot it's a real blast ...
I wish they had more 'instructions' on how to use the program itself -- e.g., how to message other players privately -- or what vocabulary is in it that results in an actual voice to the group .... but, on the other hand, the game is quite intuitive (especially for Mac users) and these things are learned fairly quickly.
