Trouble using exact_fit with Gaia and as3

Question

I'm building a flash site (with Flash CS4 and AS3) inside of the Gaia framework.
I want to let my visitors toggle between Exact_Fit and No_scale, and I've attached the following code to be triggered by the toggle button.
function toggleExactFit(event:MouseEvent):void
            trace ("Here in toggleExactFit to change StageScaleMode");
            if (stage.scaleMode == StageScaleMode.NO_SCALE)
                   stage.scaleMode = StageScaleMode.EXACT_FIT;
                   this.stage.align=StageAlign.TOP_LEFT;
            else
                stage.scaleMode = StageScaleMode.NO_SCALE;
                       //  stage.align=StageAlign.TOP_RIGHT;
            trace ("Here in toggleExactFit - stage.scaleMode now = " + stage.scaleMode);
Here are my import statements:
    import flash.display.*;
    import flash.events.*;
    import com.greensock.TweenMax;
    // Imports used by Global Navigation
    import net.kaegi.navigation.NavigationManager2;
    import net.kaegi.navigation.NavigationButton2;
    import net.kaegi.events.NavigationEvent;
    import flash.text.StyleSheet;
    import flash.text.TextField;
    import com.greensock.easing.*;
    import gs.*;
    import flash.media.*;
    import flash.text.*;
    import flash.display.StageDisplayState;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.utils.Timer;
    import flash.events.TimerEvent;
    import flash.events.MouseEvent;
    import flash.ui.*;
    //import fl.video.MetadataEvent; - ONLY with flv playback component maybe
    import flash.media.SoundMixer;
This partially works.  When the toggle button is clicked, the site does stretch out to try  to fill the whole screen, but everything is shifted down by about a  hundred pixels and to the right by a couple hundred, so I can't see the  right side or lower part of my website.  I have my stage set to 960 x  620 pixels, and I checked through my different FLAs to make sure content  wasn't spilling past that boundary.
I was trying to get help on the Gaia forums, but one of theri moderators moved the post, saying this was an actionscript question, not a Gaia issue.
So, before going back to the Gaia forums, I want to make sure I have my as3 right and haven't overlloked anythying.
Any suggestions as to what I might have messed up or how to fix it?

Thanks.  I ran the very test you suggested last night in a standalone fla and the code worked fine, and I sent a note to the moderator this morning (who'd originally pulled my thread as 'non-Gaia related').  The moderator steered me in a new direction (away from exact_fit and toward an onResize function included in Gaia) so trying to get that worked out right now.
I left my post here because I often get a more nuanced understanding of things after asking questions in the Adobe forums and I don't have much experience with exact_fit, noscale and best practices for resizing and scaling content in accord with browser changes.
Thanks for your help.
