Hi, I am currently having the same issue and working through the troubleshooting guide, but I just wanted to show you this.
[ img ]I had about 7-8 tables open when the HUD stopped appearing on most of them, but the PT3 icon didn't, and the import was running fine. The computer was having issues though, and just trying very basic things like refreshing the "find player" tab in stars was causing a momentary freeze and performance issues. Then the HUD came back on this table showing what must be all my hands from the active database!
I have a very decent PC with a 64-bit OS so I am going to work through updating postgresql from 8.3.9 to 9.x. But I just wanted to show you this because I think this is very wierd so maybe you would like me to submit a ticket?
