macromedia flash sitedesign: :brokenheart;

I'm use to using html and have built my first Flash site- done entirely in Flash.
I need to incorporate a pop-up browser window.- how do i do that!!???

Its a while since i used flash, and now im stuck trying to load a url in a new
browser window.
The flash file is incorporated through another html document.

getURL is loading a new window inside the other window, I need a getURL to
open a new window.

I know this is basic, Thanks a lot if anyone can help
