var count = 0, count2 = 0, add1 = 3, add2 = 10, timerID;
function show() {
if (ie4) {
count += add1;
count2 += add2;
delay = 30;
if(count2 > 100) count2 = 100;
if(count > 100) {
count = 100;
add1 = -10;
add2 = -3;
delay = 350;
}
if(count < 0) count = 0;
if(count2 < 0) {
count2 = 0;
add1 = 3;
add2 = 10;
delay = 200;

fader.style.filter = "Alpha(Opacity="+count2+",FinishOpacity="+count+",style=2)";
timerID = setTimeout("show()", delay);
