The proper English spelling is manoeuvre, Allan. But if 'maneuver' already is too hard for Americans to spell correctly, why not simplify it further to 'manuver'? Or still better 'manver'? Make up your minds, over there. We have enough problems already with your habit of using 'data' in stead of 'datum', 'media' in stead of 'medium' and 'z' for 's', as in 'organization'.
