I have this code to move my mc:

```php

var myTween1:Tween = new Tween(mc1, "y", Back.easeOut, 420, 0, GetRandomRange(13,18), true);

```

the movie plays fine and then after about EVERY 1 min everything just stops and stays that way forever. anyone have any idea why? or did it happen to anyone else before…

tnx for any input:beer2::beam:
