I haven't completely tracked down the code yet, but this popup is happening when you click on the multimedia link. It loads a popup in the corner of the screen, waits a few seconds, then the popup loads an ad and resizes/moves the window. Don't know if there's anything you can do about that, since disabling any onclick popups breaks legitimate stuff.
