Windows disappear when reverting to default layout

Question:

Billy: Sometimes when I try to revert to my default layout or the classic view, windows disappear. My contents menu is sometimes inaccessible!

Answer:

To return to the default layout, use Ctrl+F5. All windows should be returned to their originally saved position.

Contents menu should always be available in the contents window with a right-click (except some combinations of beginner and read-only modes). If you are not sure what level you use, you could try File : Level : Warrior to make sure all menus and options are accessible.
