I am relatively inexperienced with Flash. I know just enough to get myself into trouble as you will see here…  
I am creating a website with the bulk of the material in flash. All was going well until the client asked for a twinkling effect on the static textured background (created in PS). I was able to find a file on the web and apply that code to a flash file to create this effect. I layered this in Dreamweaver in div layer 1, the main web content (combo of html & flash) on div layer 2.  
The problem is that it slows down all my animation in the main content. Plus I previewed it on a MAC and the quick flash intro I created crawls at agonizingly slow speed!!!  
Does anyone know a better, “lighter” way to do what I need to do? here is the link to my site , in progress…

This is the AS2 code in frame 1 on “blink1000.swf” (in div layer1):

var numStars:Number = 250;  
for (i=1; i\<=numStars; i++) {  
\_root.attachMovie(“star”, “star”+i, i, {\_x:Math.random()\*Stage.width, \_y:Math.random()\*Stage.height, \_alpha:Math.random()\*100});  
\_root[“star”+i].rotSpeed = Math.round(Math.random()\*8+2);  
\_root[“star”+i].tranSpeed = Math.round(Math.random()\*10+5);  
\_root[“star”+i].tranDir = Math.floor(Math.random()\*2);  
trace(\_root[“star”+i].rotSpeed);  
\_root[“star”+i].onEnterFrame = function() {  
if (this.tranDir == 0) {  
this.\_alpha += this.tranSpeed;  
if (this.\_alpha\>100) {  
this.tranDir = 1;  
}  
} else {  
this.\_alpha -= this.tranSpeed;  
if (this.\_alpha\<40) {  
this.tranDir = 0;  
}  
}  
this.\_rotation += this.rotSpeed;  
};  
}

I know I’m missing something. Any guidance from you more learned folks would be very much appreciated!
