Hi,<BR>We have a company website where we manage different information. One of our users when they are navigating in our site gets random pop-ups. I always thought unexpected popups while surfing the web was just an advertising deal between the two sites. These popups occur on our site and I know there is no code to do it (and it only really occurs with one user). I'm curious if anyone knows how the popups are occuring. How is it triggered? (I know how to spawn a new window, but I'm curious how company "A" can cause a popup on company "B"'s site?
