Once you have hands auto importing in PT3 the HUD should appear on the table.
Make sure you are running Beta 28.1 (NOT Build 4).
You need to configure Auto Import > OnGame Configuration to where the new hand history files are being written.
XP - C:\Documents and Settings\name\Local Settings\Application Data\P5\pokersite\handhistory
Vista – C:\Users\name\AppData\Local\P5\pokersite/handhistory
(Auto Detect should find these OK)
When the HUD appears you position the stats by right click dragging.
See the HUD Guides in the
Documentation.
