Navigation Menu Border

I have implemented a dynamic navigation menu linked to a web.sitemap and css stylesheet. The issue that I cannot resolve is the border surrounding the menu item when selected. I have set all static and dynamic selected border styles to "none", but nothing seems to work. In Google Chrome and Mozilla browsers, the selected item border is orange, while in Explorer the border is just a dotted line.

The same border shows up in the default.aspx page if a new web app is created in visual studio 2010 and it also shows up if a new empty website is created and a menu added. Its just annoying...

 

There are some quirks with that control.
Post this in the ASP.NET forums and you should have several people respond back with their own resolutions.
