Snow Fall tut + Load Random movie not working right

The main swf in my website controls all the navigation and I thought it would be nifty to have this file load random swf’s in the background. These random swfs are all based on Kirupa’s falling snow tutorial, and feature different products/company logos.

When I come to run my swf, the random swf’s load in fine but the snow effect is messed up, it won’t display more than 1 falling symbol. If you run these snow fall swfs independantly then you can see they work fine, its just when they’re loaded into to something else I think. Can anyone help?

Please see the attached file: run header.fla (flash mx)
