Pop-Up Zapper Lite helps you by "zapping" away those annoying pop-up windows when you surf the web. Pop-Up Zapper Lite watches the work of your web browser and when it identifies a pop up window coming up (or pop-under), it makes it invisible and then closes it. You never see the popup window. If you set a preference for it, when you encounter a place where a click would produce a window, Pop-Up Zapper Lite will identify this recent click as a request for the window and leave it alone. See the Preferences for all the options. You can also customize a list of web sites where popups are allowed, useful for email and banking sites.You can also tell Pop-Up Zapper Lite to leave the next popup alone by pressing Command-Control-z.Command-Control-x toggles the program on or off.Pop-Up Zapper Lite can be upgraded for free to Pop-Up Zapper for OS X
