jQuery tabs problem in IE6

jQuery tabs problem in IE6

Problem now is here:
http://bit.ly/1wo95W

In IE6 you have to click a tab twice in order to display its contents.

Code:

// jquery tabbed interface
$(function () {
    var tabContainers = $('div.tabs > div');
    tabContainers.hide().filter(':first').show();
                           
    $('div.tabs ul.tabNavigation a').click(function () {
        tabContainers.hide();
        tabContainers.filter(this.hash).show();
        $('div.tabs ul.tabNavigation a').removeClass('selected');
        $(this).addClass('selected');
        return false;
    }).filter(':first').click();
});

I've tried a few ways to fix it, such as a different selector instead of 'div.tabs > div'. I've even tried repeating the line ' tabContainers.filter(this.hash).show();' in different parts of the script, but no luck!

Any ideas on how to fix it?
Thanks
