[RESOLVED] [F8] Preloader screwing up pop up window [Urgent]

[hinklej]

I've got a flash book that you can enlarges the page using the window component (scrollPane, UIscrollbar included). It was working fine but when I changed my actionscript setting to "export frame for classes ( 2) " for my preloader to work it screws the pop up window up. Is there a work around?

import mx.containers.Window;
// Popup size
popup_width = 600;
popup_height = 450;
// Zooming settings
zooming = false;
zoom_mc.zoom_in_btn.onPress = startZoomingMode;
navbar_mc.navZoom.onPress = startZoomingMode;
myBook.onClick = bookClick;
function startZoomingMode() {
    myBook.flipOnClickProp = false;
    myBook.autoFlipProp = 0;
    showZoomPointer();
    zooming = true;
}
function bookClick(pageNumber, page_mc, isCornerClick) {
    if (!zooming) {
        return;
    }
    var page_url = page_mc.URL;
    if (page_url != undefined) {
        open_popup(page_url, pageNumber);
    } else {
        zooming = false;
        myBook.flipOnClickProp = true;
        myBook.autoFlipProp = 50;
        hideZoomPointer();
    }
}
function open_popup(page_url, pageNumber) {
    if (zoom_win != undefined) {
        return;
    }
    hideZoomPointer();
    zoom_win = mx.managers.PopUpManager.createPopUp(_root, Window, true, {title:"Page Number: " + pageNumber, closeButton:true});
    zoom_win.createObject("ScrollPane", "zoom_pane", 0, {contentPath:page_url, _x:3, _y:31});
    zoom_win.setSize(popup_width, popup_height);
    zoom_win.zoom_pane.setSize(popup_width-6, popup_height-31);
    listenerObject = new Object();
    listenerObject.click = closeWindow;
    zoom_win.addEventListener("click", listenerObject);
    zoom_win._x = Stage.width/2-popup_width/2;
    zoom_win._y = Stage.height/2-popup_height/2;
}
 function closeWindow(eventObject:Object) {
 zoom_win.deletePopUp();
 zooming = false;
 delete zoom_win;
 myBook.flipOnClickProp = true;
 myBook.autoFlipProp = 50;
 }
function showZoomPointer() {
    Mouse.hide();
    attachMovie("ZoomIcon", "zoom_icon_mc", 0);
    zoom_icon_mc.onEnterFrame = function() {
        this._x = _xmouse;
        this._y = _ymouse;
    };
}
function hideZoomPointer() {
    Mouse.show();
    delete zoom_icon_mc.onEnterFrame;
    zoom_icon_mc.removeMovieClip();
}
