The web page displays properly in Firefox 39.0. Some browsers may not render a pop-up window’s width/height dimensions exactly as stipulated in the text boxes, nor comply with a 'no scrollbars' request. Use 'manual' mode if pop-up windows do not close when you click on the 'Close pop-up...' button. In 'manual' mode, close the current, and then future pop-up windows, manually. Suggested screen-size for viewing this web page: 15.4-inches or more.
