Toggle option using converted buttons

Im pretty new to using flash and actionscript and this may seem like a really silly question but here goes. Im trying to create a moving button function for a menu. The item im using is a complex shape which is converted to a button symbol. I have the piece working fine except the button only moves whilst the mouse button is being held down instead of moving after a simple click. if you use a component button you can access the parameters and set the toggle property to true. Can you do this for a button symbol? Cheers :}
