in my movie i have a bunch of MCs with an

onClipEvent (enterFrame) {}

type of code on them, which is constantly cycling when the movie is playing but is essential to my movie's presentation. Due to this, the movie takes up a massive amount of the computer's processing power and the everything becomes very sluggish. does anyone know how i can control the enterFrame cycling better so that it doesn't take up so much of the processor's power? thanks for your help!
