Bring lightweight window to the front (android)

Hey there,

(SKD: 3.1.0.GA / Android device testing LG optimus L5 )

ive got the following problem: Ive got a menu in a lightweight window so that i can animate it (gMail for android style) but when i open a couple of windows and close them and open some more and then "toggle" the menu, the menu isnt on top, so..... i am not seeing it.

this is my index.xml

<Alloy>
    <!-- load menu -->
    <Window id="menu" height="Ti.UI.FILL" width="320dip" top="49dip" left="-320dip" zIndex="100" backgroundColor="transparent" >
        <View id="menuBackground"  opacity="0.7" width="320dip" height="Ti.UI.FILL"></View>
        <WebView id="menuView" url="/html/menu.html" disableBounce="true" height="Ti.UI.FILL" left="0dip" width="267dip" zIndex="2"></WebView>
    </Window>
 
</Alloy>

as you can see only the menu is present all the other windows are opened trough my controller shown below

exports.openPage = function(controller, animated, open){
    // new window
    Alloy.Globals.windows.push(controller);
    var view = controller.getView();
 
    // open 
    if( controller.__views.scrollView.track !== false ){
 
            Ti.API.log('droid open page');
            // dont set fullscreen, navbarhidden, model or windowsoftinput mode it will make the view heavy
            view.setFullscreen(false);
            view.setNavBarHidden(true);     
            // http://developer.android.com/reference/android/R.anim.html   
            view.open({
                activityEnterAnimation: Ti.Android.R.anim.fade_in,
                activityExitAnimation: Ti.Android.R.anim.fade_out
            });
 
 
    }   
 
 
    // create crumb
    Alloy.Globals.crumbLib.crumb(controller.__views.crumb, controller.__views.scrollView);
 
        var activity = Ti.Android.currentActivity;
 
        // close item when back is pressed
        view.addEventListener('androidback', function(e) {
 
            if(Alloy.Globals.menu.left == "0dip"){
                exports.toggle('left', false);  
            }else{
                if(Alloy.Globals.windows.length > 1){
                    exports.closePage();
                }else{
                    activity.finish();
                }   
            }
 
        }); 
 
};

ive removed some iOS code because the problem only exists on android (as usual)

someone a idea?

Thanks!!
