Please regard the sticky regarding question layout.
File: menu.js
change the lines in the code to what you see below.
var HighBgColor='white'; // Background color when mouse is over
var HighSubBgColor='white'; // Background color when mouse is over on subs
var FontLowColor='black'; // Font color when mouse is not over
var FontSubLowColor='black'; // Font color subs when mouse is not over
var FontHighColor='black'; // Font color when mouse is over
var FontSubHighColor='black'; // Font color subs when mouse is over
The script then 'highlights' in the same colour as the standard menu text.
Hope this helps
