I have encountered an annoying issue with my DNN nav menu.

When you click on ANY item of the menu, a dotted line appears around the WHOLE menu... this happens whether you are logged in or not in FF but not in IE

I used the following code to

a { outline:0; }

a:focus
{
-moz-outline-style: none;
}

in my css file but it doesn't seem to have an effect.
