I'm plagued by a popup from Windows XP when I use wireless. It says, "You are in an Unknown Location..." It always pops above whatever window I'm using, but does not take focus, so while it does not interrupt my typing, it gets in the way and I can't dismiss it with a keystroke.

I'd like to find a way to disable this popup. I've searched in control panel --> Network Connections.

I'm not referring to "balloon tips" that appear related to the wireless connection in a new location.
