Preloader problem!

Hey guys,

Im having an issue with a swf file. It contains 35 pngs in the library which are called to the stage via actionscript from a movieclip, which is also called via actionscript. Every movieclip and png is set to export for actionscript on frame 3, but in the bandwidth profiler there is still a huge spike of data at the beginning, and i dont know whats causing it.

So when I try to preload the movie I get a large pause then it jumps to almost full then plays.

Ive read a lot about setting the frame for exporting, but it doesnt seem to work. Anyone have a suggestion?

Cheers,

Rab.
