Sortables on Table in IE6 causes it to crash

[jbweb]

Hi,

I use the mootools Sortables plug-in with mootools 1.2.1 on my site
for sorting pages and articles, which are displayed in a table.

All the modern browsers work perfectly, not even some errors or
notices in firebug. I tried it in FF2, FF3, IE7, Chrome, Opera, Safari
and all work normal.

But when i try it in IE6, the whole browser crashes! No error
displayed, it just closes the browser.

It's a normal Sortable as far as i know:

var ArticleSort = new Sortables('.article-list tbody', {
        constrain: true,
        handle: '.handle',
        clone : false,
        opacity: 0.5,
        snap : 0,
        onComplete: function() {
                ArticleSort.serialize( function(element, i) );
        }
});

on a normal xhtml table:

<table class=".article-list">
        <thead>
                <tr>
                        <th>name</th>
                        <th>handle</th>
                </tr>
        </thead>
        <tbody>
                <tr>
                        <td>name1</td>
                        <td><img src="/images/handle.gif" alt="Handle" 
class="handle" /></
td>
                <tr>
                <tr>
                        <td>name2/td>
                        <td><img src="/images/handle.gif" alt="Handle" 
class="handle" /></
td>
                <tr>
                <tr>
                        <td>name3</td>
                        <td><img src="/images/handle.gif" alt="Handle" 
class="handle" /></
td>
                <tr>
        </tbody>
</table>

Someone knows of this? Is it a bug?
