Embedding A SWF Scale Problems

Hello.

I’m having issues with the scale of a SWF when I embed it into another one.
The main SWF confuses the external SWF scale with wherever there’s an object on the external SWF’s stage. It doesn’t mask out the objects that fall outside of the border… Does anyone know how to resolve this issue? I’ve had this problem before and there’s got to be a simple solution for it. Any help would be greatly appreciated! Thanks!
