@Gary - no spurious happenings.
@Egg - no issues. The design file, however, is a bust.
@eselick - I took your original ask at face value.

You do not seem to need a Xara NavBar with sub-menus.
You do not need a rollover so no need for MouseOver/MouseDown actions.

This follows Egg's idea of there being a visible indication that you are on a link: CSS - Simple NavBar.xar.

If you do not want this, delete the website HTML Code (head) CSS.
The red boxes and the rest are as I described in Post#3.
