Hi, thanks a lot for your program. I have a very simple app with 3 controllers and three views. The app works perfectely when complied but I get very strange behaviours on TiShadow:

1. the background image on the gameMenu.xml Window is not displayed
2. when I make a modification (e.g. setting fullscreen="true" to fullscreen="false") and launch tishadow run I get the error "XHR Error....".
   I already tried to remove TiShadow and reinstall it and recreate the app.

• index.js

(function(){Alloy.createController("welcome").getView().open();})();

• welcome.js

function setUI(){
    this.activity.actionBar.hide();
    this.visible = true;
};

function nextPage(){
    Alloy.createController("gameMenu").getView().open();
    $.winWelcome.close();
    $.winWelcome = null;    
};

• welcome.xml

<Alloy>
    <Window id="winWelcome" backgroundColor="aqua" fullscreen="true" visible="false"  backgroundImage="background.png" onPostlayout="setUI">
        <View id="viewMain" layout="vertical" visible="true">
            <View id="viewUp" height="50%"></View>
            <View id="viewDown" height="50%"  layout="vertical">
                <View id="viewBtnContinue" height="20%">
                    <Button onClick="nextPage">NEXT PAGE</Button>
                </View>
                <View id="viewBtnCredits" height="20%">
