is there 100% working pop-under script?

or the browsers today are more smart then all the programmers?

all the one i found are working on IE only, and even not on 9, that also blocked it....

any idea?

Clicksor's code is amazing if you could reverse engineer...

What a lot of adult sites do is have a null links so on any click it spawns a popunder. With the exception of 0-Day exploits it's d@mn near impossible to launch a popup/under without some type of user interaction.
