We have a SharePoint 2010 publishing site (migrated from 2007 via db-attach), and we have a custom master page for the site. But whenever I access files under _layouts/ (eg ManageFeatures.aspx, settings.aspx), the custom master page is used. How can I make it use the v4.master for the files under _layouts, but keep our custom master page for the actual sites? Is it even possible in 2010?
In 2007, some of the _layouts (eg ManageFeatures, settings.aspx) do not seem to use the custom master page.
