[jQuery] superfish and other jquery scripts conflict in IE 7

[shenny]

Hi,

I'm using superfish for this website i'm working on while using other
scripts that are all under jquery. Basically I have 3 sets of
navigation going on. 1. main navigation using superfish 2.sidebar
using spritefade 3.three huge panels that are links and do a simple
fade when hovered. I've put the superfish script last on the on window
ready function and as soon as i load it in IE, it disables the effect
of all the scripts. However, if i take out superfish script then the
effects of the other scripts come back. Here's the scripts i have
now:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/
jquery.min.js" type="text/javascript"></script>
<script src="js/spriteFade.js" type="text/javascript"></script>
script src="js/superfish.js" type="text/javascript"></script>
        <script type="text/javascript">

 $(document).ready(function(){
                $('.categoryNav').sprites({
                        show: {opacity: 'show'},
                        hide: {opacity: 'hide'}
                });
                //
                $('.fade').hover(function(){
                        $(this).fadeTo("slow", 0.25);
                        }, function(){
                                $(this).fadeTo("slow", 1);
                });
                //
                $('ul.nav').superfish({
                        autoArrows: false,
                        dropShadows: true,

                });
});

        </script>



Could there be an internal script conflict and if so can this be fixed
so that all scripts are happy with each other? If you think it's other
things conflicting let me know and I can provide the scripts for
you.

Any help or input would certainly be appreciated :)
