Preloader/transition question

i did the preloader/transition tut. in this site… it works great… but one thing i noticed that i the transition during the closing part is still showing the previous .swf file… and i dont want the previous .swf file to show while the transition is closing…

does anyone know how to make this happen?

if i didnt explain it very well, you can take a look at what i mean by going here…

i dont have a preloader for the main.swf so please be patient when the screen turns white… it will turn black and have a bar scroll across the screen when its loaded…

thanks
