oneguy,

document.cookie="name=value; Path=/bla/bla/";

не помогает, вот полностью javascript:

document.cookie="name=value; Path=/"
function setcookie(a,b,c) {if(c){var d = new Date();d.setTime(d.getTime()+c);}if(a && b) document.cookie = a+'='+b+(c ? '; expires='+d.toUTCString() : '');else return false;}
function getcookie(a) {var b = new RegExp(a+'=([^;]){1,}');var c = b.exec(document.cookie);if(c) c = c[0].split('=');else return false;return c[1] ? c[1] : false;}


var ie=document.all
var dom=document.getElementById
var ns4=document.layers
var calunits=document.layers? "" : "px"

var bouncelimit=32 //(must be divisible by 8)
var direction="up"

function initbox(){

  if (!dom&&!ie&&!ns4) return;
  crossobj=(dom)?document.getElementById("dropin").style : ie? document.all.dropin : document.dropin
  scroll_top=(ie)? truebody().scrollTop : window.pageYOffset
  crossobj.top=scroll_top-250+calunits
  crossobj.visibility=(dom||ie)? "visible" : "show"
  dropstart=setInterval("dropin()",25)
}

function dropin(){
  scroll_top=(ie)? truebody().scrollTop : window.pageYOffset
  if (parseInt(crossobj.top)<100+scroll_top)
     crossobj.top=parseInt(crossobj.top)+40+calunits
  else{
     clearInterval(dropstart)
  }
}

function bouncein(){
  crossobj.top=parseInt(crossobj.top)-bouncelimit+calunits
  if (bouncelimit<0){ bouncelimit+=8;
      bouncelimit=bouncelimit*-1;
  }

  if (bouncelimit==0) clearInterval(bouncestart)
}

function dismissbox(){
  if (window.bouncestart) clearInterval(bouncestart)
  crossobj.visibility="hidden"
}
function truebody(){
   return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}

function dropornot(){
  if (!getcookie("droppedin")||!getcookie("Session")){ //Если хотя бы одного кука  нет  - перезапускаем
     setcookie("Session",true) ;//Кук на сессию;
     setcookie("droppedin",true,01*60*1000) ;

     window.onload=initbox; //Запуск 
 }
} dropornot();
