How to detect window version ?

Hi,

Here it is:

var agt = navigator.userAgent.toLowerCase();

var nn = ((agt.indexOf('mozilla') != -1) &&
((agt.indexOf('spoofer') == -1) &&
(agt.indexOf('compatible') == -1)));
var ie = (agt.indexOf("msie") != -1);
var mac = (agt.indexOf("mac") != -1);
var sun = (agt.indexOf("sunos") != -1);
var win = ((agt.indexOf("win") != -1) || (agt.indexOf("16bit") != -1));

Regards,
Lisa
