barra de navegacion

[dewars]

Hola!! No soy muy experto en Flash, pero empiezo a hacer mis pinitos y he hecho una barra de navegacion para mi web. La barra funciona de tal manera que cuando pones el raton sobre uno de los menus aparece, debajo de la barra, los submenus (ej.- menu---->>> boton1 | boton 2 |boton3.....)
El codigo que tiene es el siguiente:

Código:

//ON ROLL OVER's:
boton1.onRollOver = function(){
boton1.gotoAndStop(2)
boton2.gotoAndStop(1)
boton3.gotoAndStop(1)
boton4.gotoAndStop(1)
boton5.gotoAndStop(1)
boton6.gotoAndStop(1)
_root.movie1.play()
movie1._visible = true
movie2._visible = false
movie3._visible = false
movie4._visible = false
movie5._visible = false
movie6._visible = false
}
boton2.onRollOver = function(){
boton1.gotoAndStop(1)
boton2.gotoAndStop(2)
boton3.gotoAndStop(1)
boton4.gotoAndStop(1)
boton5.gotoAndStop(1)
boton6.gotoAndStop(1)
_root.movie2.play()
movie1._visible = false
movie2._visible = true
movie3._visible = false
movie4._visible = false
movie5._visible = false
movie6._visible = false
}
boton3.onRollOver = function(){
boton1.gotoAndStop(1)
boton2.gotoAndStop(1)
boton3.gotoAndStop(2)
boton4.gotoAndStop(1)
boton5.gotoAndStop(1)
boton6.gotoAndStop(1)
_root.movie3.play()
movie1._visible = false
movie2._visible = false
movie3._visible = true
movie4._visible = false
movie5._visible = false
movie6._visible = false
}
boton4.onRollOver = function(){
boton1.gotoAndStop(1)
boton2.gotoAndStop(1)
boton3.gotoAndStop(1)
boton4.gotoAndStop(2)
boton5.gotoAndStop(1)
boton6.gotoAndStop(1)
_root.movie4.play()
movie1._visible = false
movie2._visible = false
movie3._visible = false
movie4._visible = true
movie5._visible = false
movie6._visible = false
}
boton5.onRollOver = function(){
boton1.gotoAndStop(1)
boton2.gotoAndStop(1)
boton3.gotoAndStop(1)
boton4.gotoAndStop(1)
boton5.gotoAndStop(2)
boton6.gotoAndStop(1)
_root.movie1.play()
movie1._visible = false
movie2._visible = false
movie3._visible = false
movie4._visible = false
movie5._visible = true
movie6._visible = false
}
boton6.onRollOver = function(){
boton1.gotoAndStop(1)
boton2.gotoAndStop(1)
boton3.gotoAndStop(1)
boton4.gotoAndStop(1)
boton5.gotoAndStop(1)
boton6.gotoAndStop(2)
_root.movie1.play()
movie1._visible = false
movie2._visible = false
movie3._visible = false
movie4._visible = false
movie5._visible = false
movie6._visible = true
}
//ON PRESS':
boton1.onPress = function(){
boton1.gotoAndPlay(3)
}
boton2.onPress = function(){
boton2.gotoAndPlay(3)
}
boton3.onPress = function(){
boton3.gotoAndPlay(3)
}
boton4.onPress = function(){
boton4.gotoAndPlay(3)
}
boton5.onPress = function(){
boton5.gotoAndPlay(3)
}
boton6.onPress = function(){
boton6.gotoAndPlay(3)
}
//ON RELEASE's:
boton1.onRelease = function(){
boton1.gotoAndPlay(2)
}
boton2.onRelease = function(){
boton2.gotoAndPlay(2)
}
boton3.onRelease = function(){
boton3.gotoAndPlay(2)
}
boton4.onRelease = function(){
boton4.gotoAndPlay(2)
}
boton5.onRelease = function(){
boton5.gotoAndPlay(2)
}
boton6.onRelease = function(){
boton6.gotoAndPlay(2)
}

Quisiera saber si hay alguna forma de que los submenus desaparezcan si no los utilizas. Es decir, si paso el raton por encima de la barra pero lo quito sin darle a ningun boton la barra vuelva a su primer estado. ¿alguien tiene alguna idea?
