The popups you're talking about in the last couple of posts (Marje and Bigchuck) are different from what the thread is about. There is another type, essentially a system message that Microsoft built into the Windows system that is meant for networked computers to use to deliver System message. But some spammers have figured out how to discretely get their message to travel to and appear on your screen in the Messenger Service window. They always say "write this message down" because the text cannot be highlighted or clicked on.

Go back and look at the earlier link with an example of one.
