Open browser window within flash app

Hello,
I am building a kiosk app in flash and need to open browser windows whenever there is a URL link. The problem is that when the browser window opens, the fullscreen flash becomes a resizable window and the user has to close the window and open the flash app again to make it full screen again. So i’m wondering if there’s any way I can open a browser window within the flash app sort of like an iframe or lightbox pop up? I’ve heard of this Native Window thing but I’m not sure what that is.

Any help would be appreciated.
