jquery sortable triggers clicks on links in firefox 3.0


I'm using jquery 1.2.6, and jquery-ui 1.6rc2. I have a table as
follows:
<table class="newtable" id="contentTable">
    <tbody id="contentList" class="ui-sortable">
    <tr>
        <td >
            <a href="editContent.html?id=109&amp;fass=12">
                        U.S. Military: Afghan Police Officer Kil...
                    </a>
                </td>
    </tr><tr>
        <td >
            <a href="editContent.html?id=101&amp;fass=12">
                        Category 3 Hurricane Omar Slams Northern...
                    </a>
                </td>
    </tr>
</table>
This is defined in my script section:
            $(document).ready(function(){
                $("#contentList").sortable({
                    axis: 'y',
                    placeholder: 'blah'
                });
                enableTooltips("contentTable");
            });
The problem I'm having is that when I'm in firefox, and I happen to
grab the link to start dragging, when I let go, firefox fires the
click on the link, navigating the user away from the page. I can't
figure out how to prevent that from happening. I've tried messing with
the stop function, but neither event.preventDefault(); nor
event.stopPropagation() seem to prevent the link from being clicked.
Any help is appreciated.
