centering a pop up

[suikoden]

Hey guys, first post ever. So show me som love and answer. thanks:D

Basically, i want a window that pops up in the center of the page regardless of the users resolution.

so far i have these scripts which work fine:-

<script language="JavaScript">
function openNewWindow(URLtoOpen, windowName, windowFeatures) { newWindow=window.open(URLtoOpen, windowName, windowFeatures); }
</script> //in my head tag

<a href="#" onclick="window.open('main.htm','enhanced','width=550, height=400, left=0, top=0, toolbar=no, scrollbars=no, status=no, resizeable=no, fullscreen=no')"> //for the link

how can i modify that to get my window to center on the click?

cheers

Note that your page must be accessible to users with JS disabled. The above script will load in the same window if that is the case.
