at least that's what i think it is.
for one site i go to i have to use IE (normally i use firefox). occassionally when i go to this site and click a link, another page comes up that says, "Please wait while we load your ad or click continue to go to your page". regardless of whether i wait or click IE starts spawining window after window. hundreds of them.
using task manger i kill IE and go back to the site and it works perfectly.
