/*

For simplicity, each of the 9 menu items has its own set of two functions rather than a single, hard to decipher function.
OnMouseOver, it shows a hidden div containing the menu and changes the background of the menu heading.
This is done by switching CSS styles.

The background image has a habit of flickering; this needs to be ironed out.
