Stage conflict problem

Hello guys, im really getting crazy about this one… im doing a site and i did it by creating the site section as external swfs.

Heres the problem. I created my own scrollbard class and used it on one of the external swf. its working by its own, but the moment i loaded it on my main swf, the listeners attached to the stage of the external swf is conflicting with the main swfs stage. I can fix this by using ADDEDTOSTAGE event, but with this i cant, because i have a mouseevent.MOUSE_UP that will remove a listener from the stage. I also try to create a stage reference that will be placed on the added to stage event handler but its still the same.

any advice as3 gurus?
