The externally-hosted ad stuff is blocked with AdblockPlus, the
specific one I'm referring to is inline javascript, not loaded from an
external host, so it can't be blocked (without blocking all
javascript). It is the popurl function at the bottom of the page (I'm
sure email will horrible mangle this, my apologies in advance):

function popurl(url)
{
                                var popunder=new Array()
                                popunder[0]=url;
                                var p
='width=800,height=510,scrollbars=1,resizable=1,toolbar=1,location=1,menubar=1,status=1,directories=0';
                                var one_time=0
                                function get_cookie(Name) {
                                                var search = Name + "="
                                                var returnvalue = "";
                                                if
(document.cookie.length > 0) {
                                                offset =
document.cookie.indexOf(search)
                                                if (offset != -1) { //
if the cookie exists
                                                offset += search.length
                                                end =
document.cookie.indexOf(";", offset); // set the index of beginning
value
                                                if (end == -1) // set
the index of the end of cookie value
                                                end = document.cookie.length;

returnvalue=unescape(document.cookie.substring(offset, end))
                                                }
                                                }
                                                return returnvalue;
                                                }
                                                function loadornot(){
                                                if (get_cookie('popunder')==''){
                                                load_pop_power()
                                                document.cookie="popunder=yes"
                                                }
                                                }
                                                function load_pop_power(){

win2=window.open(popunder[Math.floor(Math.random()*(popunder.length))],"bw",p)
                                                win2.blur()
                                                window.focus()
                                                }
                                                if (one_time==0)
                                                load_pop_power()
                                                else
                                                loadornot()
}

And then:
popurl('http://www.bharatstudent.com/study-abroad/studyabroad.php?refcode=Ziddu');

The page (the bharatstudent.com site in this case) is what opens
automatically, without any user interaction. I've blacklisted both
ziddu.com and bharatstudent.com from opening pop-ups, but it still
happens to me. Yes, I could just disable javascript but I'm more
curious about why this particular bit of code is able to bypass the
pop-up suppression rules.

Thanks,
Paul
