It is possible in IE. Not in NS 4.x and unsure in Mozilla.
In IE:
<SCRIPT LANGUAGE=JavaScript FOR=window EVENT=onbeforeunload>
var strMsg = 'Press Cancel if you wish to save your form before leaving\nIf
you press OK you will lose all unsaved information.';
if (!top.ButtonClicked) {
window.event.returnValue = strMsg;
}
</SCRIPT>
