Atrazar execução de um Script

Bom dia pessoal, to com um popup aqui queria que ele demorasse um pouuco mais para ser carregado!

Ja tentei com sleep() mais ele atraza o conteudo todo da pagina

if (window!=top)
top.location.href=location.href

var persistclose=0 //set to 0 or 1. 1 means once the bar is manually closed, it will remain closed for browser session
var startX = 375 //set x offset of bar in pixels
var startY = 80 //set y offset of bar in pixels
var verticalpos="frombottom" //enter "fromtop" or "frombottom"
var displaymode="oncepersession"
function iecompattest(){
return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}
function closebar(){
if (persistclose)

document.cookie="remainclosed=1"
document.getElementById("tamindir_topbar").style.visibility="hidden"
}
function staticbar(){
barheight=document.getElementById("tamindir_topbar").offsetHeight

var ns = (navigator.appName.indexOf("Netscape") != -1) || window.opera;
var d = document;
function ml(id){
var el=d.getElementById(id);

if (!persistclose || persistclose && get_cookie("remainclosed")=="")
el.style.visibility="visible"

if(d.layers)el.style=el;
el.sP=function(x,y){this.style.left=x+"px";this.style.top=y+"px";};
el.x = startX;
if (verticalpos=="fromtop")
el.y = startY;

else{

el.y = ns ? pageYOffset + innerHeight : iecompattest().scrollTop + iecompattest().clientHeight;
el.y -= startY;
}
return el;
}
window.stayTopLeft=function(){
if (verticalpos=="fromtop"){
var pY = ns ? pageYOffset : iecompattest().scrollTop;
ftlObj.y += (pY + startY - ftlObj.y)/8;
}

else{

var pY = ns ? pageYOffset + innerHeight - barheight: iecompattest().scrollTop + iecompattest().clientHeight - barheight;
ftlObj.y += (pY - startY - ftlObj.y)/8;
}
ftlObj.sP(ftlObj.x, ftlObj.y);
setTimeout("stayTopLeft()", 10);
}
ftlObj = ml("tamindir_topbar");
stayTopLeft();
}

if (window.addEventListener)

window.addEventListener("load", staticbar, false)
else if (window.attachEvent)
window.attachEvent("onload", staticbar)
