When I click on a web part on the SharePoint page the header disappears and the ribbon then displays. How can I prevent the header from being replaced by the ribbon? It is ok that the ribbon is displayed when a web part is clicked however I would like the header to also remain on the page permanently.
Oddly enough, this is an intended behavior of SharePoint 2010 though your guess is as good as mine as to why. Basically, you will need to create a custom master page and move things around a bit to prevent this from happening. Heather Solomon has an excellent post that covers how to fix this problem.
