Dunno if anyone else had this problem..didn't see it on the suggestions so far, but so far only thing that annoys me is the fact that sometimes it attempts
to move an object [i.e. a barrel] rather than activating/opening it and vice versa. This results in alot of irritating clicking especially on those small items. Maybe (1) type of double click system? I.E double click to activate/open something.

(2) Or the NWN style
where you click and hold and a menu would pop up from where you can select
what you want to do to the object....this might be more interesting since you can then add alot of things you can do to an object. Also might make it easier to pick up certain things too, alot of things 'activate' when you actually want to put it on your inventory etc etc.
