Accordian height animation problem

Accordian height animation problem

I'm having some kind of animation problem with my accordian. For one of the panels I have set a fixed height. This naturally changed the height of the other panels. So I changed the autoHeight property, but this seems to cause some animation problems. When I switch from the large panel to the other ones I get some bad jerky animation which seems to fly around the page until it settles. Any ideas how to fix this?

In my .js file I have

$(function(){
    $("#accordion ").accordion({
        autoHeight: false,
        fillSpace: true,
        clearStyle: true,
    });
});
