Rotating portfolio

Hi everybody
I have a so called carousel portfolio on www.car-wash.net
my index page, so called business card is loading an swf which is portfolio.
when its opening a new window it shows in the center but if i maximize the index page an then call portfolio file then my carousel shows at the right side of the stage , although the frame which is in the same portfolio swf file stays in the middle (frame is placed on the stage of the fla and the icond of the portfolio are png filed placed in the xml file) in my AS code i have
var centerX:Number = Stage.width/2;
var centerY:Number = Stage.height/2;
i am publishing both files 100% x 100% no scale
so it should load straight in the middle, both stages are havingthe same W and H, so i dont really get where the problem is
THe most weird thing is that if i put in portfolio
var centerX:Number = Stage.width[COLOR=red]/3.2;[/COLOR]
var centerY:Number = Stage.height/2;
then it is on maxilized screen straight in the middle
in my index page i even tried to load the swf through

var myClip = this.createEmptyMovieClip("myMc", this.getNextHighestDepth());
var myLoader = new MovieClipLoader();
var myListener = new Object();
myListener.onLoadInit = function () {
};
myLoader.addListener(myListener);
myLoader.loadClip("portfolio.swf", myClip);

I find it not logical at all
PLEASE help me, cos i spent many slepless nights trying to figure this out_NO RESULT
