hello,

With the script below I am making a ball move from left to right and back. but when I rollover twice quickly, it also accepts the second rollover command. I would like it to accept that second rollover only when the first one is finished. I mean, I want the first to be finished before it accepts another rollover.  
I know it is simple to solve this with a tween using frames instead of as, but I was wondering if someone knows how to adapt the script.

> on(rollOver){  
> ballTween = new mx.transitions.Tween(balMC, “\_x”, mx.transitions.easing.Regular.easeOut,balMC.\_x, 44, .5, true);  
> ballTween.onMotionFinished = function() {  
> ballTweenterug = new mx.transitions.Tween(balMC, “\_x”, mx.transitions.easing.Regular.easeOut, 44,11.9, .5, true);  
> Thank you!
