onRollOut not alway working?

programming flash

I will keep the question simple for now and provide example if needed.

I just have a simple button set up to move a [COLOR=DarkOrange]BOX[/COLOR] on rollOver using tweens and move it back into position onRollOut.

**Problem: **
The onRollOut function doesn’t work consistantly. It works ok most of the time, but if I move the mouse quickly (not like crazy quick), the [COLOR=DarkOrange]BOX[/COLOR] doesn’t get back into place.

Is there a way to “secure” an onRollOut statement to make sure it works at all time?

I try also adding onReleaseOutside, onDragOut… but that is not the problem.

Thanks
