The event is only dispatched to the body element once in Opera, so you
could add the listener there instead.
As the body property of the document object will initially be null, you
have three options:
1. <body onresize="/* ... */">
2. <body>
<script type="text/javascript">
document.body.onresize = function() {
/* ... */
};
</script>
3. <head>
<script type="text/javascript">
this.onload = function() {
document.body.onresize = function() {
/* ... */
};
};
</script>

All versions of Opera that dispatch the resize event (from 7.0, onwards)
will act as intended.
Just in case you care: IE will still fire multiple times, and Firefox
only supports the first option (it doesn't dispatch the event to the
body element at all).
