I've modified the breadcrumb on my master page to mimic the breadcrumb style from 2007 by copying the 2007 code over:
<span class="ms-mwstitlearea">
<asp:ContentPlaceHolder ID="PlaceHolderTitleBreadcrumb" runat="server">
<asp:SiteMapPath SiteMapProvider="SPContentMapProvider" ID="ContentMap" SkipLinkText="" CurrentNodeStyle-CssClass="breadcrumbCurrent" NodeStyle-CssClass="ms-sitemapdirectional" runat="server" />
</asp:ContentPlaceHolder>
</span>
However, on the site settings pages, the breadcrumb turns into a hybrid of 2007 and 2010 styles where it's vertically listed with right arrow images between the levels. How can I change the site settings pages to use the 2007 breadcrumb style?
