Hi,

I’m curious, I’ve been testing how to search for specific movieclip on stage and came a cross the typeof operator.  
So my test was creating ten movieclips on stage and then trace them with a for loop, like this:

```php

var count:Number = 10;
for (var i = 0; i<count; i++) {
    attachMovie("myMC", "my"+i+"_mc", this.getNextHighestDepth());
    var my_mc:MovieClip = _root["my"+i+"_mc"];
    my_mc._x = 5+40*i;
    my_mc._y = 5;
    my_mc.id = i;
    my_mc.nmb_txt.text = i;
}
my_btn.onRelease = function() {
    for (var prop in _root) {
        if (typeof _root[prop] == "movieclip") {
            myNmb_txt.text += " "+_root[prop].id;
        }
    }
};

```

When I run this I get as expected ten movieclips on the stage, but when the typeof loop runs the output is:  
“9 9 8 7 6 5 4 3 2 1 0”.

So my question is, where did the duplicate “9” come from?
