The Zyberweb Editor is in the tinted region at the top of the page.
When it is running, you will be able to see a toolbar of coloured icons. Can you see this toolbar?
☺I can see the toolbar - The Editor is running.
☹ I can't see the toolbar buttons - Click the "Start Editing" button
☹ There is no "Start Editing" button - click the "Zyberweb™ Editor" button at the bottom of the screen then click "Start Editing"
