Challenge to Center Working Preloader

I’m in a bit of a pickle and can’t sort my way out.
I’m loading an external swf that has a preloader on Scene 1, and the main content on Scene2. While the content on Scene 2 centers nicely, the preloader content refuses to do so, lol.
Here’s what I’ve got on my main project timeline:

mcHMI.onRollOver = function() {
 this.gotoAndPlay("over");
 }
 mcHMI.onRollOut = function() {
 this.gotoAndPlay("off");
 }
 
 mcHMI.onRelease = function() {
 getURL("http://www.hermanmiller.com", "_blank");
 }
 
 mcCOI.onRollOver = function() {
 this.gotoAndPlay("over");
 }
 mcCOI.onRollOut = function() {
 this.gotoAndPlay("off");
 }
 
 mcCOI.onRelease = function() {
 getURL("http://www.contemporary.ab.ca/", "_blank");
 }
 
 
 
// No scaling and align to top left
Stage.scaleMode = "noScale";
Stage.align = "TL";
 
// Create listener object for when the stage is resized
var stageListener:Object = new Object();
Stage.addListener(stageListener);
setBackground();
// Call function when the stage is resized
stageListener.onResize = function() {
setBackground();
}
function setBackground() {
// Position background to middle
bg._x = Stage.width/2;
bg._y = Stage.height/2;
mcMenuBarTop._x = Stage.width/2;
 
 
 
// Scale background to fit width and height
bg._width = Stage.width;
bg._height = Stage.height;
// Check if background grew bigger on x or y and
// adjust other to match to maintain aspect ratio
bg._xscale = bg._yscale = Math.max(bg._xscale, bg._yscale);
}
// Content floating in middle
container._x = Stage.width/2;
container._y = Stage.height/2;
 
sizeListener = new Object();
sizeListener.onResize = function() {
 container._x = Stage.width/2;
 container._y = Stage.height/2;
 
};
Stage.addListener(sizeListener);
 
 
 
//start Stage re-size code
Stage.align = "TL"; 
Stage.scaleMode = "noScale";
// ---> Create a new listener object
var stageListener:Object = new Object(); 
// ---> Define the resize function...
stageListener.onResize = function() { 
      // ---> first, get the new dimensions of the stage....
      var stageWidth:Number = Math.round(Stage.width);
      var stageHeight:Number = Math.round(Stage.height);
   trace("Stage size is now " + Stage.width + " by " + Stage.height);
 
   mcTitleMCmain._x = stageWidth1;
   //mcTitleMCmain._y = (stageHeight/1.35) - (mcTitleMCmain._width/1) ;
 
   btn1._x = stageWidth1;
   btn1._y = stageHeight-50;
 
 
 
   btna._x = stageWidth-53;
   btna._y = stageHeight100;
 
   btng._x = stageWidth-114;
   btng._y = stageHeight80;
 
   btne._x = stageWidth-166;
   btne._y = stageHeight80;
 
   btnb._x = stageWidth-219;
   btnb._y = stageHeight80;
 
   btnc._x = stageWidth-269;
   btnc._y = stageHeight80;
 
   btnd._x = stageWidth-185;
   btnd._y = stageHeight80;
 
   btnf._x = stageWidth-268;
   btnf._y = stageHeight80;
 
 
   mcButton1a._x = stageWidth-220;
   mcButton1a._y = stageHeight80;
 
   btnHermanMillerMC._x = stageWidth-113;
   btnHermanMillerMC._y = stageHeight-50;
 
   btnMCDesigner._x = stageWidth-40;
   //btnMCDesigner._y = stageHeight200;
 
   btnMCSustain._x = stageWidth-100;
   //btnMCSustain._y = stageHeight200;
 
   container6._x = stageWidth-560;
   container6._y = stageHeight-350;
 
 
   btnR1._x = stageWidth1;
   btnR1._y = stageHeight-320;
 
 
   mcMenuBarBottom._x = Stage.width/2;
   mcMenuBarBottom._y = stageHeight-61;
 
Stage.align = "LT";
Stage.scaleMode = "noScale";
//
myListener = new Object();
myListener.onResize = centercontent;
Stage.addListener(myListener);
//
function centercontent() {
wallPaper_mc._x = Math.ceil(Stage.width/2-wallPaper_mc._width/2);
wallPaper_mc._y = Math.ceil(Stage.height/2-wallPaper_mc._height/2);
**[COLOR=teal]container1._x = Math.ceil(Stage.width/2-container1._width/2);[/COLOR]**
**[COLOR=teal]container1._y = Math.ceil(Stage.height/2-container1._height/2); [/COLOR]**
 
 
    mcContactNames._x = Math.ceil(Stage.width/2-mcContactNames._width/2);
    mcContactNames._y = Math.ceil(Stage.height/2-mcContactNames._height/2);
 
 mcAboutUs._x = Math.ceil(Stage.width/2-mcAboutUs._width/2);
    mcAboutUs._y = Math.ceil(Stage.height/2-mcAboutUs._height/2);
 
}
//
centercontent();
 
 
};
// --->  Apply the listener...
Stage.addListener(stageListener); 
// ---> Run the function...
stageListener.onResize(); 
//--------------------//

container1 listed above is what I’m dumping my swf into…

A button brings you to the actionscript on the main timeline that calls the swf file:

this.createEmptyMovieClip("container1", 15); 
var mclListener:Object = new Object(); 
mclListener.onLoadInit = function(mc:MovieClip) {//is now loaded and initialized in flash,- ready to center 
    mc._x = Stage.width/2 - mc._width/2; 
    mc._y = Stage.height/2 - mc._height/2; 
} 
var image_mcl:MovieClipLoader = new MovieClipLoader(); 
image_mcl.addListener(mclListener); 
image_mcl.loadClip("ASK-Bimages.swf", container1); 
centercontent();
 
};
// --->  Apply the listener...
Stage.addListener(stageListener); 
// ---> Run the function...
stageListener.onResize(); 
//--------------------//

ASK-Bimages.swf has the preloader on Scene 1. Pretty basic stuff. Here’s the actionscript:

totalBytes = this.getBytesTotal();
loadedBytes = this.getBytesLoaded();
remainingBytes = totalBytes-loadedBytes;
percentDone = int((loadedBytes/totalBytes)*100);
totalBytes = this.getBytesTotal();
loadedBytes = this.getBytesLoaded();
remainingBytes = totalBytes-loadedBytes;
percentBar = int((loadedBytes/totalBytes)*100);
percent = int((loadedBytes/totalBytes)*100);
percentDone = percent+"%";
bar.gotoAndStop(percentBar);
if (_framesloaded == _totalframes) {
 gotoAndPlay(3);
}

As mentioned, the swf loads just fine and stays centered at any resize. The preloader will jump to another position when you resize.
Any help would be greatly appreciated.
Tnx
