jquery.autocomplete doesn't work in compability mode

Question

I've read all the results I can find on SO about this without finding anything that applies to me, so don't judge me too quickly :)

I am using jquery.autocomplete downloaded from here: http://www.dyve.net/jquery/?autocomplete together with http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.js

This all works well in IE8 and FF, but as soon as I activate compability mode in IE8 I keep getting:

Microsoft JScript runtime error: Object doesn't support this property or method

When looking in the call stack, This is the one where it breaks:

<script type="text/javascript">
    $().ready(function() {
$("#123").autocomplete("www.google.se");
}); 


</script>

and then the calling function is this:

    if ( jQuery.readyList ) {
        // Execute all of them
        jQuery.each( jQuery.readyList, function(){
            this.call( document, jQuery );
        });
        // Reset the list of functions
        jQuery.readyList = null;
    }

where this line throws the error:

this.call( document, jQuery );

Does anybody know why this happens? As mentioned above, works super in IE8 and firefox, but not in compability mode(IE7)

EDIT: changed the autocomplete code to have no dependencies on methods or textboxes

Add Firebug Lite to the page and then use console.log() to find out which object and method the error is referring to.
