Flash 8 button

Hi, well if anyone can help me a million thanks!

Ok, so basically when you create a button and customize it blahblahblah…in the over state (or when you click it) if you want like a movie/animation to play you have to hold the left click until it finishes or else it will just stop playing/disappear…is there anyway to avoid this??? I mean to display whatever movie/animation you want with just one click, without having to hold the click on the button?

:S…■■■■ i hope i made myself a little clear
