I have the pt3 demo, and when playing sngs, tourneys, or non heads-up cash games, the hud works fine. During hu cash games the heads up display does not appear. Pokertracker is still recording the hands but im not getting any hud stats. Sorry if im missing something really obvious, but I can't figure out what's wrong. Also, i have a mac if that makes a difference.

Is this with the 20-100BB tables at PokerStars? If so this is a known issue that will be resolved in our next beta release.

Yeah, it's the 20-100bb tables, thanks for the reply.
