I second that. If you click around the inventory, all is well, but as soon as you click a HUD, the eyes are off the targetted item again. When clicking on HUD while taking photos, this is a bad thing.
For me at least clicking the HUD shouldnt change the looking direction either.
And yes, the way other TPVs do it, is rather bad. Standing there, talking to someone and staring forward and ignoring the person you are talking to is no good at all. ;-)
