title: asp.net menu control staticBottomSeparatorImage appears underneath horizontal menu
body: <p>I'm using the ASP menu control, .NET 4.0. I finally got the styles working thanks to the answer on <a href="https://stackoverflow.com/questions/2655377/how-to-style-an-asp-net-menu-with-css">this post</a> but now that I've set the controlRenderingCompatibilityVersion in my web.config to "4.0" I'm seeing my separator image underneath the Menu control. </p>
  
  <pre><code>&lt;div class="menuContainer"&gt;
          &lt;asp:Menu ID="_menu" runat="server" EnableTheming="true" DataSourceID="_siteMap" CssClass="menuClass" IncludeStyleBlock="false" 
              Orientation="Horizontal" StaticBottomSeparatorImageUrl="../images/menuSepImage.jpg" OnMenuItemDataBound="_menu_OnDataBound"&gt;
          &lt;/asp:Menu&gt;
          &lt;asp:SiteMapDataSource ID="_siteMap" runat="server" ShowStartingNode="false" /&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>I tried pulling out the default CSS styles that are auto-generated, and setting IncludeStyleBlock="false" but setting the #_menu img.horizontal-separator {} class in my CSS doesn't do anything, which is why I'm trying to set it with the StaticBottomSeparatorImageUrl property.</p>
