hi,
i found this preety powerful script:

<script>

// Amazing Frameless Popup Window - Version I
// (C) 2000 www.CodeLifter.com
// Free for all users, but leave in this header

// set the popup window width and height

var windowW=250 // wide
var windowH=400 // high

// set the screen position where the popup should appear

var windowX = 250 // from left
var windowY = 100 // from top

// set the url of the page to show in the popup

var urlPop = "framless2.htm"

// set the title of the page

var title = "Page Title"

// set this to true if the popup should close
// upon leaving the launching page; else, false

var autoclose = true

// ============================
// do not edit below this line
// ============================

s = "width="+windowW+",height="+windowH;
var beIE = document.all?true:false

function openFrameless(){
if (beIE){
NFW = window.open("","popFrameless","fullscreen,"+s)
NFW.blur()
window.focus()
NFW.resizeTo(windowW,windowH)
NFW.moveTo(windowX,windowY)
var frameString=""+
"<html>"+
"<head>"+
"<title>"+title+"</title>"+
"</head>"+
"<frameset rows='*,0' framespacing=0 border=0 frameborder=0>"+
"<frame name='top' src='"+urlPop+"' scrolling=auto>"+
"<frame name='bottom' src='about:blank' scrolling='no'>"+
"</frameset>"+
"</html>"
NFW.document.open();
NFW.document.write(frameString)
NFW.document.close()
} else {
NFW=window.open(urlPop,"popFrameless","scrollbars,"+s)
NFW.blur()
window.focus()
NFW.resizeTo(windowW,windowH)
NFW.moveTo(windowX,windowY)
}
NFW.focus()
if (autoclose){
window.onunload = function(){NFW.close()}
}
}

</script>


what i'm interested in is the autoclose-upon-leave part of this code. i modyfied this a bit and got something like this:

var lg = null;
var zamknij = true
function go(){
lg=window.open("page.htm")
lg.focus()
if (zamknij){
window.onunload = function(){lg.close()}
}
}

but this code is odd - sometimes it works, sometimes it doesn't (on the page that i rewrote it on everthing was just fine, but on the page that i actualy wanted to use this i get 'awaiting an object' message and nothing happens) and so i was wandering if i got this good. maybe there is another way of writing the same (one that woulg work for me)

my regards
mike
