Components and preloader : export class on frame 2

Hello,
I was looking for a way to display a preloader that start from 0%… I have a basic preloader working on 3 frames on a 1st scene, going to the 2nd scene when done loading… Well that works but it doesn’t start at 0%. So i tried the “publish on frame2” trick, but the components i use aren’t loaded if i do that…
So is there a way to display a good preloader that starts at 0% with a movie that contains components??

Thanks…
