I downloaded and installed the new version 3.08 tonight. I allowed PT to update the database. I ran Housekeeping, as recommended. (And, just in case it matters, I'll add that I had to run Housekeeping twice. My computer, which is becoming unreliable and which I am in the process of replacing, crashed during the first attempt.)
Now, for some reason, the stats showing up for my opponents at the table are for the current session only. I'm used to the stats being this way for me, but now it's as if everyone at the table is "Hero" as far as the HUD is concerned.
