I have a custom RadMenu skin that I created and had styled how I wanted. We recently upgraded our project to the newest version of Telerik, and I have noticed a white border around my sub menus (on the top, left, and right sides) that wasn't there before, and I can't figure out which styling combination will remove it. I noticed that this border also appears on the menu in the RadMenu overview (http://www.telerik.com/help/aspnet-ajax/menu-overview.html). I have attached this photo with a black box surrounding the white border I am talking about. Can someone help me remove this border?
