A couple of questions for a PSS A3xx newcomer

Hi guysWas wandering if anyone could answer a couple of questions for a PSS A3xx newcomer.The first is that i seem unable to "nail" a catIII ils landing at rwy 05 egss, landing stansted. The landing in itself is ok, the problem is that the a/c seems to be following the wrong heading for stansted during short finals as it touches down just to the right of the r/w then attempts to follow a path that gradually diverts away from the r/w. When programming the RAD/NAV, after insering the ils frequency for stansted's ils 05, the CRS states a heading of 048 degrees. However, all published data on this rwy give the heading as 046 degrees - could this possibly be the problem as the a/c does seem to divert away from the correct rwy heading by about 2 degrees. If this is the case, is there anyway of either "correcting" the heading for stansted or override the automatic heading of 048 degress that the fmc puts in ?The second question, totally unrelated, is that if i expand the pd by clicking on it whilst in the compact view, the expanded display gets placed 'behind' the main instrument panel and hence, disappears. The only way to read it is to go to the ifr view and move the expanded display to a postion that will place it above the top of the compact instrument panel.Any help on either question much appreciatedThanksGary
