Does anyone know if the iHwy jQuery ListNav Plugin works on jQuery 1.4? I'm trying to implement it on my current site, but its not doing anything. It isn't generating any errors, but isn't working either. I've double checked the code, though to have more eyes, here is the code:

-- On the page itself

            <div id="myList-Nav" class="listNav"></div>
            <ul id="myList">
              <li><a href="major1">major1</li>
              <li><a href="major1">major1</li>
              <li><a href="major1">major1</li>
              <li><a href="major1">major1</li>
              <li><a href="major1">major1</li>
              <li><a href="major1">major1</li>
              <li><a href="major1">major1</li>
                .... dynamically generated list of 100 or so
            </ul>

In my JS file:
        $("#myList").listnav({
            includeAll: false, 
            noMatchText: 'There are no matching entries.'
        });

and I'm using the CSS from the demo site just to get it going:
.listNav { margin:0 0 10px; }
.ln-letters { overflow:hidden; }
.ln-letters a { font-size:0.9em; display:block; float:left; padding:2px 6px; border:1px solid silver; border-right:none; text-decoration:none; }
.ln-letters a.ln-last { border-right:1px solid silver; }
.ln-letters a:hover,
.ln-letters a.ln-selected { background-color:#eaeaea; }
.ln-letters a.ln-disabled { color:#ccc; }
.ln-letter-count { text-align:center; font-size:0.8em; line-height:1; margin-bottom:3px; color:#336699; }
