Centering a popup window?

[TeeMouse]

I am creating a Flash site that opens a popup window when the user clicks a
button. I have been able to edit the html code, using notepad, to achieve this,
however the popup automaticaly appears in the top left corner of the screen.
does anyone know what code I need to make it appear in the centre of the screen?

I would apreciate any help you could offer.

Try this. Just fix a few things. It will work.

++ place this in the head tag ++

function MM_openBrWindow (theURL, winName, features){
var popup_width=731
var popup_height=316
var screen_width=window.screen.width
var screen_height=window.screen.height
var popup_left=Math.round((screen_width-popup_width)/2)
var popup_top=Math.round((screen_height-popup_height)/2)

newwindow=window.open(theURL,"gallery","height=" + popup_height + ",width=" +
popup_width +
",menubar=0,resizable=0,scrollbars=no,status=0,tit lebar=no,toolbar=0," +
"left=" + popup_left + ",top=" + popup_top);
if (window.focus) {newwindow.focus()}
}


++ place this in the map area ++

onclick="MM_openBrWindow('home.html')"
