When you use Microsoft PowerPoint to make courseware or show slides, you'll get the same thing: when you play a slide, you want to implement a slide that, without human intervention, automatically goes back to the beginning after the slide is played to the end.

In the pop-up dialog box, select the Loop show in Show options, press ESC to terminate check box, as shown in the following illustration. Click OK to close the dialog box.
