Small "flashing" problem during transition between Swfs

Hi there
i´m currently testing a navigation sistem for a website i´m building.

I´m using the actionscript of the external swfs transitions tutorial and it is working fine.

Basicly the animation is a centered box opening and closing. When you click o a button the "outro animation plays (the box closes) and then it loads the external Swf (witch starts by opening the box).

**The problem is that after the swfs “outro” animation plays and the next swf is loaded there is a quick “flash” that breaks the continuum of the movie.
I know the “flash” thingy happens because of the loading process but i want to know if there´s a way of stopping this little flash from happening while loading the external swfs.
