pop-up window when user leaves site

[haroonqurehi]

I want to pop-up window when user leaves site (either by closing browser window or going to any other site). I dono want a popup as long as user browses within the domain.

Please share your ideas.

My idea is that pop ups are evil. Leave the poor user alone when they want to leave your site.

I wish I could but this is client's requirement.
