Smooth Mouse ON / Mouse OUT

Hi guys
Have a look at the script below. I have a button that has some actions when I mouse over… right now, when you mouse OUT it choppily goes back to it’s normal state and I was wondering if there was something I could put in the code so that even if you quickly mouseON and then mouseOUT, the whole movie plays out… so that the transition flows smoothly…

on (rollOver) {
tellTarget ("/design") {
gotoAndPlay (“1open”);
}
}
on (rollOut) {
tellTarget ("/design") {
gotoAndPlay (“1close”);
}
}

on (release) {
getURL(“design.html”);

}
