Hello there  
I have this class:

class TestButton  
extends Button  
{  
public function onRollOver()  
{  
trace(“onRollOver”);  
}  
}

I want to create an instance of this class by using the flash 8 environment. Nevertheless, when I choose convert to symbol, I just can choose among Graphic, Button and MovieClip. Does anyone know how could I create a shape like a square and make it an instance of TestButton?  
Thanks in advance
