PokerTracker

I play Rush Omaha cash almost exclusively. Recently, whenever I use PT3.10 on my iMac, the hud shows names/stats for the player that was sitting in that seat LAST hand! Have tried manually deleting hand-history files from the FT folder and starting one or the other of FT / PT3 first...

The HUD should not work at all at Rush tables on Mac, because Mac OS security prevents applications interacting with each other as PT3 needs to do to support Rush tables.

Please enable logging and restart PT3 then play a few hands at a single table and attach your PokerTracker.log file to a Support ticket along with the hand history file for the session.

Aha! I must have been confused about the sudden change in behavior. I also have a PC that I play on (though I'm on my mac more frequently). Guess I'l have to stick to the PC. Thanks!

If you could submit those logs though we would appreciate it - since it's a hand behind it sounds like it's doing something and we'd love to know exactly what's going on.
