how many pop-ups telling you how many pop-ups have been blocked have been blocked.

I don't know how anyone dares to use a laptop in a presentation any more, what with any number of popups that could appear at any time. [It's been 30 days since your last order of Fungus-B-Gone! Do you want to purchase now?] I guess you could disconnect the computer from the Internet but that wouldn't stop the popups on your computer related to internal timing, or warning you that you're not connected to the Internet.
