PokerTracker

The stats of players at the bottom of my screen blocks some of the action buttons.

Is it possible to configure each players stats.. move them a little to the right or left etc?

If so.. how do I do this? I am playing on iPoker network.

Do you mean PAHud, or do you mean the HUD in PT3?

PAHud; go to Options -> Layout Manager, select your site and table size and then move your stats to where you like.

PT3; right click drag the stat groups; then PT-icon -> Save Layout when you're done.
See the HUD Guides in the Documentation and the How To: HUD Configuration for more info.
