What the hell??

[Granny]

It appears I'm being stalked by some pop-up thing on USMB with a savage of some kind wielding a sword. What's up with that?

It was happening to me as well a couple of weeks ago. I enabled my pop-up blocker, and it's been ok since. Now I get a message on the bottom of my monitor that pop up has been blocked, which is still an inconvenience.
