Home and Menu Layers do not hide
The Course Introduction slide is the first page you see. These icons work fine.
When you click start, this takes you to the Menu Slide. The navigation icons will be used on every slide. When you hover over the Home Icon, the Home Layer will show. When you hover over the Menu Icon, the Menu Layer will show. If your mouse leaves the menu on any layer, the menu should display only the Home Icon and the Menu Icon. These layers do hide when you select the Close Home or Close Menu icons.
