Hi there;  
I want to make a Mc fade in when mouse gets over it and fade out when mouse gets away, just like “onMouseOver” command of java script.  
The problem is , when i use rollOver command flash thinks that , the MC i used, is a button.But it is not. Ýt is a complex MC includes lots of buttons, tweens vs… So all inside the MC not works.  
How can i fix that?  
I am posting the fla files to make the problem more clear…  
It is already fading but the buttons inside the Mc called “musicsection” are not working…  
I will be glad if anyone solves this problem :rambo:
