There is logo on the top (image as link) and other images as links. These links are not working in FF and safari. The problem is with css/ul/li based navigation menu. If I remove the menu html code, images as links are working fine. The css based navigation menu is based on this code:

/* Navigation Menu */
#nav a, #nav a:hover, #nav a:focus {...}
#nav {...}
#nav ul {...}
#nav .menu .level1-li {...}
#nav .menu a {...}
#nav .menu a.level1-a {...}
#nav .menu .sub {...}
#nav .menu .sub a {...}
#nav .menu a:hover {...}

I am not much familiar with CSS and this is the example I have downloaded from the web. It seems "a" is doing something wrong here.
