freelancer wasnt designed to operate in widescreen mode, its a modification that just expands your view. the HUDs will always be in the same spot. cant be moved.
when i tried this once for widescreen TV, the HUDs did the same thing.
as far as i know, it cant be fixed. maybe it can with some crazy more in-depth INI editing, but the anti-cheat would probably pick up on the modification.
