I tried it last night and it"s actually very straight forward to configure. I"m not that impressed though - the stats seem to appear and then disappear again at will, and the table appears and disappears from the main control window.
Also, the default setting is for the stats to be opaque, and if you are sat in the top right hand seat at a 10 seated iPoker table, it covers your right hand card completely....... as I found out last night when I had an ace in the left hand card, but want sure about the right hand card so just flat called just in case...... then switched off the HUD, and saw I had aces!
