Hello, Kirupians.  
I have question regarding slideTo option [lmc tween prototype].

Let’s say there is a button and when you rollover on that button, other objects starts to fall down. And when you rollout, the object moves back to the original position.  
For example -\>

> 

button.[color=black]onRollOver[/color] = function() {  
obj1.tweencolor=black  
};

button.onRollOut = function() {  
obj1.tweencolor=black  
};

When I applied above codes and rolled over then rolled out, it seemed to work fine at first sight. Yet, when I moved my cursor to the button back and forth constantly, objects began to fly over to some random place.  
Is there a way to prevent this problem? I tried .null like (obj1.\_y.null) but it won’t work at all… Please help… Thank you!
