For ages Safari was doing very well with pop-ups (and still is). However, I have started to see a rise in 'pop-under' ads which it is less good at dealing with (you tend to notice them when you close the Safari window and see an advert for '1000 smileys!' lurking beneath like a woodlouse). I am guessing Apple are not going to address this, but am I the only one who has noticed this rise in pop-unders?
