I was creating a game in MX 2004, everything was fine, then just 5' later, everything stop working, even a button.

I have this button:_root.mcBttScreen.btOpen and the following code

_root.mcBttScreen.btOpen.onPress = function (){
_root.mcBttScreen.play();
}

they were wfine, then they stop, so I have to move the code inside the button and using on(press) to fix it

Anyone knows about this?
