mouseEnabled=false triggering a MOUSE_OUT

If I set the mouseEnabled property of a button to false, it automatically triggers the MOUSE_OUT (and ROLL_OUT) event.

Is there a way of avoiding this? I don't want any events to be active after setting this property. I attached an FLA, also here is the code:

Actionscript Code:

exterior_btn.addEventListener(MouseEvent.CLICK, Click);
exterior_btn.addEventListener(MouseEvent.ROLL_OVER, Rollover);
exterior_btn.addEventListener(MouseEvent.ROLL_OUT, Rollout);
exterior_btn.mouseChildren = false;
exterior_btn.buttonMode = true;
exterior_btn.useHandCursor = true;

function Rollover(e:MouseEvent):void
{
    trace('Rollover');
}

function Rollout(e:MouseEvent):void
{
    //trace('\n'+e+'\n');
    trace('Rollout');
}

function Click(e:MouseEvent):void
{
    exterior_btn.mouseEnabled = false;
}

Thanks

oK I figured it out:

Actionscript Code:

function Rollout(e:MouseEvent):void
{
    if (e.target.mouseEnabled)
    {
        trace('Rollout\n'+e+'\n');
    }

}

function Click(e:MouseEvent):void
{
    e.target.mouseEnabled = false;
}
