Hi,
I am having a problem with my dropdown menus as they continue to stick after they have returned. Here is the code, any help would be amazing.
var DDSPEED = 10;
var DDTIMER = 15;


function ddMenu(id,d){
var h = document.getElementById(id + '-ddheader');
var c = document.getElementById(id + '-ddcontent');
clearInterval(c.timer);
if(d == 1){
clearTimeout(h.timer);
if(c.maxh && c.maxh <= c.offsetHeight){return}
else if(!c.maxh){
c.style.display = 'block';
c.style.height = 'auto';
c.maxh = c.offsetHeight;
c.style.height = '0px';
}
c.timer = setInterval(function(){ddSlide(c,1)},DDTIMER);
}else{
h.timer = setTimeout(function(){ddCollapse(c)},50);
}
}
// collapse the menu //
function ddCollapse(c){
c.timer = setInterval(function(){ddSlide(c,-1)},DDTIMER);
}

function cancelHide(id){
var h = document.getElementById(id + '-ddheader');
var c = document.getElementById(id + '-ddcontent');
clearTimeout(h.timer);
clearInterval(c.timer);
if(c.offsetHeight < c.maxh){
c.timer = setInterval(function(){ddSlide(c,1)},DDTIMER);
}
}


function ddSlide(c,d){
var currh = c.offsetHeight;
var dist;
if(d == 1){
dist = (Math.round((c.maxh - currh) / DDSPEED));
}else{
dist = (Math.round(currh / DDSPEED));
}
if(dist <= 1 && d == 1){
dist = 1;
}
c.style.height = currh + (dist * d) + 'px';
c.style.filter = 'alpha(opacity=' + (currh * 100 / c.maxh) + ')';
if((currh < 2 && d != 1) || (currh > (c.maxh - 2) && d == 1)){
clearInterval(c.timer);
}
}

Also, I have tried
window.onscroll = function onPagescroll() {
var combo = $find('<%= RadComboBox1.ClientID %>');
combo.hideDropDown();
};

But obviously, to no avail.

This problem occurs in all browsers.
