[jQuery] cluetip missing the hover "?"

[Margie]

I have a table and am trying to make one of my td elements have a
cluetip.  I get the tooltip, but the cursor doesn't change to a
question mark when I hover over the text.  My td looks like this:

<td class="tooltip" title="ur_1,ur_2,ur_3,ur_4"> ur_1,ur_2,...</td>

My ready function contains this:

    <script type="text/javascript">
        $().ready(function() {
          $('.tooltip').cluetip({cursor: 'help'});
        });




I do get the "?" when I copy the examples from the demo, IE, something
like this:
<p>
<a class="load-local" href="#loadme" rel="#loadme">HOVER OVER ME</a>
</p>

    <script type="text/javascript">
        $().ready(function() {
            $('a.load-local').cluetip({local:true});
      });
    </script>

Is there special behavior with <a> tags?  All of the examples use
those, so I'm not sure if using cluetip on other tags is my problem?

Thanks,

Margie
