Using a complex button that uses nested MCs as more of a menu that also includes additional content that only displays on rollover from Kirupa’s tute  
[http://www.kirupa.com/developer/mx2004/button\_effect.htm](http://www.kirupa.com/developer/mx2004/button_effect.htm)

```auto
stop(); // stop the movie clip from playing (stop button from growing, we want that when the mouse rolls over only
            
this.onEnterFrame = function(){
 if(rewind == true){ //if rewind switch is set to true play backwards
  prevFrame(); // play backwards
 }
}
this.onRollOver = function(){
 //getURL("javascript:pageTracker._trackPageview('/ads/dillards300x600/rolloverTwo/');");
 rewind = false; //set variable (or switch) that decides wether or not to play backwards...
 play(); // play this movie clip.. (grow the button(tween));
}
this.onRollOut = function(){
 rewind = true; //set or rewind switch to true so it will play backwards...
}

```

Am I correct in thinking that the additional content does not load until encountered and technically the k weight of each of these nested MCs does not influence how long it takes this SWF to be ready to play.

I am very k weight conscious & this is something I have always wondered about.
