onMouseWheel problem

[cristi_b_1]

Hi all,
I have a scrolling dynamic text, and I made it support mouse wheel also.
The scrolling text is part of a movie that loads externally (on _level2).
I am making a site with the main menu on a level, and the other pages load on _level2 (so all pages are loaded externally, including the page with the scroller). I am saying this because my problem occurs when I visit another page (load another page on _level2), and then I come back to the page that contains the scroller (load the scroller movie on _level2) the mouse wheel works wird, meaning it scrolls more than it did last time.
So the first time you visit the scrolling text page, the mouse wheel scrolls about 20 pixels with every scroll, if I press a button to visit another page and then come back, the mouse wheel will scroll about 60 pixels with every scroll, and so on. The distance keeps increasing, only if I go to another page and then come back. Weird ain't it?

Here is the code (the onMouseWheel code is at the end)

import mx.transitions.*;
import mx.transitions.easing.*;

var First=_level3.loadXMLS[_level3.firstMovie]


var _css = new TextField.StyleSheet(); 

function loadXML(loaded) {
    if (loaded) {
        _root.info = this.firstChild.childNodes[0].firstChild.nodeValue;
        _root.heights = this.firstChild.childNodes[1].firstChild.nodeValue;


        _css.load("colors.css"); 
        _css.onLoad = function(){
        main.scroller.styleSheet = _css
        pageTitles.styleSheet = _css
                _level3.preloader_mc.stop ()
        _level3.preloader_mc._visible = false
        TransitionManager.start(_root.content_mc, {type:Wipe, direction:Transition.IN, duration:1, easing:Strong.easeOut, startPoint:6}); 
}; 


        main.scroller.htmlText = _root.info
        main.scroller.html = true
        main.scroller.styleSheet = _css
        main.scroller.autoSize = "left";
        main.scroller.text = _root.info;




        if(main.scroller._height < mask_mc._height){
            up_btn._visible = false;
            dragger._visible = false;
            bar._visible = false;

        }


        bottom = /*(main._y+mask_mc._height-main._height)*/ - _root.heights

    }
}

Does anybody have any ideas on how to fix this?
Thank you so much
