Need help with complex button rollover effects in Flash MX

Hi

I read the article about complex button RollOver/RollOut effects (http://www.kirupa.com/developer/mx2004/button_effect.htm) but i found that when i press ctrl+enter to view the button the animation plays to the last frame and doesnt go back to the start until i rollover it, then it resets and works properly. Does anyone have any idea why this is happening and how i can fix it? Im using flash MX. Also, how can i change the hit area for a button that’s been made this way?

Thanx

thats a dumb way to make tweened rollovers i reckon…it use an onEnterFrame wastes CPU no point…
