getURL...easy, resize

Good Morning Flash Fans!

I’ve got a custom button with a function that loads a URL in a new window as such:

contactus_btn.onRelease=function () {
getURL("", _blank);

That’s pretty easy, but I’d like to have the button open the window to a specific size, like a pop-up to certain dimensions.

The AS 2.0 dictionary/help files doesn’t show me how to do that. :book:

Any ideas?
