Dirty Popup This script is really mean and dirty! Put it into your webpage and the script automatically opens a popup-window. When you try to close this popup-window two more popup-windows appear. Try to close these windows and four new popup-windows appear and so on. No panic! After displaying a certain (adjustable) amount of popup-windows the script stops creating new popups and you may close the windows. Easy installation and configuration. IE4+,NN6+. Try to close the red window in order to test the script.
