We are setting up a public computer in our local tourism visitor center for people to check information on area lodging. We have created icons on the desktop for each establishment's web page, so when someone dbl clicks the icon, the web page comes up in the browser. When a second person comes, a new tab gets opened up, and so on until the browser is full of tabs. We can't get each person to close the browser or to close the tab he or she used, so we would like an option when someone clicks an icon for a web page, that the web page gets opened in the currently existing and displayed tab (replacing the contents of that tab).
