    var ie4 = 1;

    function mouseon(link) {
    if (ie4 == 1) {
        link.style.color='#FFFFFF';
    }
    }
   
    function outcolor(link, farve) {
    //    link.style.color='#000000';
    link.style.color=farve;
    }
   
    function mouseoff(link) {
    if (ie4 == 1) {
        setTimeout("outcolor(" + link.id + ", '#EEEEEE')",120);
