Preloader loading sequence

I’ve made this preloader out of the Tween Preloader AS Tutorial, and I’ve used the book script. The problem is that if you run the download simulation I dunno why, but in the 1st frame Flash puts the two bigest bitmaps that are used in Scene 2 (scene 1 is the preloader), so the preloader doesn’t really work …

Here is the code:
