Do I have to account for the event handlers beeing run in *arbitary 
order*? I have not tested this very much, but the events seem to fire in 
the same order they have been attached to the object. But that's maybe luck?
<<<<<<

From what I've seen, they're called in the _inverse order_ from which they
are assigned.  I recall messing with this a while back and deciding to avoid
adding the multiple methods to the same node and propagation type (e.g., an
img can have onload and onmouseover, but not two onloads).  I may have come
to that conclusion from reading the W3C, but I'm not certain.

Also, I think you meant to say that the "functions tied to the event
handlers" seem to execute in the same order -- if you're switching gears and
talking about when different events are fired, I have indeed seen
discrepancies between browsers.

I made the quick test below to validate the inverse order thing...this
alerts "banana" and then "apple" in both FF and IE.

-ryan

<html>
<head>
<script>
function apple () {
	alert("apple");
}

function banana () {
	alert("banana");
}

if (window.attachEvent) {
	window.attachEvent("onload", apple);
	window.attachEvent("onload", banana);
} else {
	window.addEventListener("load", apple, false);
	window.addEventListener("load", banana, false);
}
</script>
</head>
<body>This is a test.</body>
