ActionScript 2.0 :: Link A Button To A Website With New Window?

I am using Flash Cs4 and I want to open a website window with a button click, but I want the window to open seperately without closing the first webpage. When the button is clicked, I want the user to see both pages open and in order to navigate back to the original, have them click the open window of the page instead of using the back button. It would be perfect if the second window would open smaller than the original webpage, sort of minimized, so that they can still see the original pages content. I can use either actionscript 3, or actionscript 2. Whichever will acomplish the task. I am having the damdest time finding the correct code to do this. I have Flash Cs4, currently set to publish as actionscript3 with Flashplayer 10. I can change that to actionscript2 and Flashplayer 8 if anyone can give me the actionscript2 code to accomplish this task. Here is the code I am currently using to navigate to the second webpage, and yes I know it is currently actionscript 3, and this an actionscript 2 forum: Either code will work for me as long as it does the job.

addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
function mouseDownHandler(event:MouseEvent):void {
navigateToURL(new URLRequest("https://mycw3.eclinicalweb.com/cent/jsp/login.jsp"));
}

It does open in a second window with no back button as I want, as long as I am testing the movie in Flash. When I publish it to the web on a server, you still have to use the back button to go back the original page which is not what I want.
