Ok, I attached listener on Mouse and it doesn’t work in Firefox… works fine in IE and standalone…

it goes something like this:

```auto
var mouseListener:Object = new Object();
    mouseListener.onMouseWheel = function(delta) {
        var delta;
        if (delta>3) {
            delta = 3;
        }
        if (delta<-3) {
            delta = -3;
        }
        _root.speed += delta/2.5;
        if (_root.speed>7) {
            _root.speed = 7;
        }
        if (_root.speed<-7) {
            _root.speed = -7;
        }
    };
    //    
    Mouse.addListener(mouseListener);

```

I can’t find anything on the net nor Kirupa forum… why it doesn’t work in FF?  
please help…
