I’m very confused. When I instantiate a class, I’m assuming that the object is reset to its default variable values. Not so. Consider this:

```auto
class ClassTest extends MovieClip{
    var arr:Array = new Array();
    function ClassTest(){
        trace("length="+arr.length);
        arr.push(1);
    }
}

```

If I put an instance of this class on each of 2 scenes, the output is:

```auto
length=0
length=1

```

…even if the two objects have different instance names! It’s as if it is making my arr variable static by default, and not resetting it to a new array in the second instance. How do I get around this? Do I need to somehow have this code instantiate itself with something like “this = new ClassTest();”

Thanks for any help!
