Hopefully this should be a simple one!  My current code:

<script language="JavaScript">
<!-- hide

function openPopup() {
  popupWin ='enrollment_request.htm','open_window','status,dependent,width=450,height=315,left=0,top=0')
// Default (to show available options) below:
// popupWin ='','open_window','menubar,toolbar,location,directories,status,scrollbars,resizable,dependent,width=640,height=480,left=0,top=0')

// done hiding -->


<a href="javascript:openPopup();">here</a>

First, is this code a good balance between compatibility and simplicity?  I am coding this at work and need to make it simple enough for future people to edit the page without any scripting background.

Second, I want to center the window, both height and width, according to the the resolution of the user's computer.  If the res. was set to 800 x 600, the left side of the window would pop at ( 800 - 450 ) / 2 = 175 and the top would pop at ( 600 - 315 ) / 2 = 142.5 (or 143)... but also if the user's resolution was 1024 x 768 it'd evaluate that and do left side at ( 1024 - 450 ) / 2 = 287 and top side at ( 768 - 315 ) / 2 = 226.5.

Thanks in advance!
