loading multiple flash files in background

as i promissed i give a short explenation of that topic: i have built my website with 18 diffferent flashfiles. i know that is a lot, but i have 3 galleries and 4 sound files which are all seperated movies.

1) the first movie is the main movie with animation and menu and it loads a cuple of other movies in different levels! this is important. for example:if you load 2 movies on level 3, only the second movie will be finished, the first will not load.

2) the first movie you load, is a movie with a rectangle with the backgroundcolor of the mainmovie. i have loaded it on level 7. so it loads first and you don't see the others movies which i load later on level 1-6.

3) on buttonklick in the menu, you unload level 8 and load the movies on level 8.
so only one movie is in front and all the other ar hidden behind the rectanglemovie on level 7.

4) level 9 i used for the sound-files. so i can stop them with unload level 9.

thats it in short. hope it helps. with this method you can load the bigsize files in background (you can see that when you load the files the first time, then in the right upper corner you see the %-progress).
