From the developer: "Javascript PopWin EX is a Javascript-producing design tool for creating popup window which will load the specified page into the popup window. The popup window can be closed automatically after specified time. Script can be customized highly and easily by using Script Configuration Program. You can define time, size and style for the script. You don't need to write any code by yourself. Script Configuration Program will generate it for you. You can preview the script in your favorite web browser without quitting the program. All relative files that you need to upload to server will be saved along with the project file so that you can easy to get them and publish them to Internet. A detailed document will help you to master anything about this script. But in most cases you can finish the design work without reading anything from document."
