Loading an external swf into a level

Hi guys i am tring to load an external swf into my main swf in level 1 but the child swf is transparent and iif i roll over the child when is loaded the buttons underneath on the main swf are active and their sound and actions too.i can just put a big button on the child as a background and it won’t do that anymore but then the all child swf will look like a big botton .
what should i do …i want to be able to go back into the main from the child.
thanks
