Problems loading an external swf with levels

well, i will try to explain to you with my bad english.

I have a movie called plano.swf in a level 0, this movie has a button that load an external swf on level 1

but i have a problem with this:

the first movie (plano.swf ) contains a lot of buttons, and when a call an external swf, all this buttons are still there.

I don´t see it, but the cursor change (hand).

i want to block all the buttons on level 0, when i load an external swf

thanks a lot!!!
