I have a preloader (preloader.swf) which loads a form (offerte.swf).

I’ve put the this.\_lockroot on the “application” timeline on the first frame of the “Flash form application” (offerte.swf).  
But the combobox components still won’t work.

I had it working before, but suddenly it seemed to stop! Now I can’t get it get to work again.
