On the site [http://www.figleaf.com](http://www.figleaf.com) the guy has an effect that fades the main window out whenever you mouse over the navigation bar. Does anyone know how that was done?

You should’ve been more specific! It fades AFTER you’ve clicked on a button.  
It just changes the alpha of the other stuff…

on(rollOver) {  
mc.\_alpha = 25;  
}  
on(rollOut) {  
mc.\_alpha = 100;  
}  
mc is the mc that’s alpha you want to change! and alpha is in percents
