Sometimes plugin will not load resources

Hi,

I often get the following result when I try to view my webapplication via the "file:///" protocol (windows):
I don't know if it is a problem of the protocol, but however I need to fix this.
I call the plugin like:

``` javascript
(function(global) {
var VRSFramework = function(){

/**
* Inits the component
*/
function init(){

}

// Preload resources and call init function
$(function () {
$("body").queryLoader2({
barColor : "#efefef",
backgroundColor : "#111",
percentage : true,
barHeight : 1,
minimumTime : 200,
fadeOutTime : 500,
onComplete: function(){
init();
}
});
});

return this;
};
var tmpVRSFramework = new VRSFramework();
})(this);
```

I already tried to remove all CSS (background-images also), but that will not solve the problem. What can I do to debug this issue? Or what could be the problem?
