OK, I'm going to move this to the PT3 section of the forum.
The HUD configuration is shared between 6-max and full ring tables, so the popups should work in the same way.
I suspect this is to do with the amount of data needing to be retrieved from the database for your own stats.
Have you run Housekeeping recently, to make sure the cache is up to date? This should really help.
You could also try (as an experiment) unchecking the 'filter by current cash level' option - I don't think that will make any difference, but it will help narrow things down.
If you still don't see your own popup stats after re-caching, Please
enable logging, reproduce the problem by playing a few hands on a single table and submit your PokerTracker.log and PokerTrackerHUD.log files (zip/compress them first, call it logs.zip) to the
Support system , and link to this thread in the reference field of the ticket so that we can investigate.
