Reposting the example because of text-wrap in last post :

-function openPP(a1){
-wWidth=500;wHeight=30;
-relWid=(a1?screen.width:window.innerWidth)/2;
-relHgh=(a1?screen.height:window.innerHeight)/2
-wLeft=(relWid>wWidth/2)?relWid-wWidth/2:screenX
-wTop=(relHgh>wHeight/2)?relHgh-wHeight/2:screenY+10
-window.open("about:blank",
"newP","left="+wLeft+",top="+wTop+",width="+wW idth
+",height="+wHeight)
-}
-</script>
-</head>
-<body style="text-align:center">

button>

screenX/screenY works in mozilla only. In opera and IE, it doesn't
work. So check the browser and for other browsers, use screenLeft/
screenTop.

I hope you meant "check the feature" when you said "check the browser".

I was going to say that but then i was not sure about which feature
will be available in Mozilla but not in Opera, IE and maybe other
browsers.

That is why you feature detect for screenX or whatever it is that might
work. If the browser supports it, then you use it. If it doesn't, then
you don't worry about it.
