Preloader problem

Hello everyone.
I’ve got a problem.
I’m building a preloader, i’ve made 2 keyframes, each has stop(); in the beginning. The first keyframe shows all the loading progress and when it’s done, it jumps to the second keyframe, but the problem is that my frame 1 is starting to play only after the whole flash is loaded. I want to make that the first frame is loaded and it shows all the progress of the downloading flash movie
