ActionScript 2.0 :: Opening Popup Page In Standalone Projection

I am creating a standalone projector (CD with autorun). This means my swf files are NOT contained within html. I would like to, when clicking on button, open a popup html page with specific dimensions. I was wondering if it is possible to do that, and what AS to use,
or if I have the obligation, to openpopups, to launch my swf files within html mother page.

Here is the code of button that works (but does not open popup):
on (press) {
getURL("URL", "_blank");
}

Here is the code for popup but does not work (opens html page normally):
on (press) {
getURL("URL", "", "width=580,height=400,left=100,top=100");
}
