Opens a window that will close itself after a pre-set time. The popup can be launched from a link in your page, or automatically when the launching page loads. Very well behaved, and does not launch multiple windows on re-clicks.
A not so common method to close windows is using a 'click anywhere' method. The code specifies that if the popup loses focus or is clicked the popup closes. Basically anywhere you click will close the window.
Use this code to make sure a window remains in focus, on top. Great for web site news or smaller popup windows that are easily shuffled under out of focus.
