PokerTracker

The HUD is apparently not identifying where players are ACTUALLY sitting, so the stat overlays are over the wrong players/the REPLAY HAND thing is totally screwed up. How do I fix this?

PokerStars MTT, Vista.

Several Replayer bugs are fixed for the next release.

Did it work properly before you re-installed? What did you re-install, PT3? Did you uninstall and install, or install over the top?
Are you using preferred seating?
Try re-installing Pokerstars too.

It worked fine before the reinstall. I reinstalled both PStars and PT3, hoping to fix some OTHER HUD issues (like stats not appearing/no popup in cash games). I am using preferred seating. It was a clean uninstall. I'll reinstall PStars again once today's big tourneys are over.
