Button onRollOver Issue

I am trying to use the onRollOver method to have a button adjust the alpha properties of a separate movie. When the mouse is over the button, the movie’s alpha property changes to 100%, thus appearing on the screen. Conversly, when the mouse moves off of the button, the movie’s alpha property changes to 0%, disappearing.

My problem is that during run time, the first pass of the mouse over the button does nothing but the second and subsequent passes work perfectly.

What am I doing wrong and how can I get it to work the first time the mouse passes over the button?

I’ve attached the Flash file as an example.

Thanks!!!
