The WYSIWYG editor is designed to show the page as it looks each time the learner clicks Next in the player (iterations). By default, when you click the Graphics tab, the graphics appear in the first iteration, which is what the learner will see upon first viewing the page in the player. Using SHIFT+Click in the WYSIWYG editor, you can:
invoke the available player actions (such as hotspots or animations)
see hidden graphics (that would be normally be viewed or invoked in other iterations of the page)
