I am working on a file that emerges with a vibration / random alpha effect, but I don’t want the effect to last forever… I want it to stop.  
Here’s my code, which is placed on the first keyframe (actions) in the timeline:

var vibration = 0;  
var xShift = random(vibration \* 2+1) - vibration;  
var yShift = random(vibration \* 2+1) ± vibration;  
\_root.logoBlurIn.onEnterFrame = function() {  
\_root.logoBlurIn.\_x += xShift;  
\_root.logoBlurIn.\_y += yShift;  
\_root.logoBlurIn.\_alpha = random(100);  
};

After a few moments, I want it to come into focus (end of timeline has a normal image, in focus).

How do I stop this crazy thing??? :sen:
