I have a Visual Studio 2010 C++ project which was copied from another visual studio project and renamed. The project compiles fine and works. However recently, I went to the Resource View to edit some dialogs and the window is completely empty. I can’t remember if I went there since I copied the project or not:

Any ideas on how I can get this back? I’m thinking there is some cache somewhere?
UPDATE
I should add that this solution is a multi-project solution and normally in the resource view even if a given project does not have resource files you will still see a “folder” for the project in the resource view tree view. There are no “folders” for any of the projects in the solution.
I should also add that other solutions that I open in visual studio will display the resource view fine.
I had similar problem that I solved with reloading projects in the solution (unload projects and then reload all projects).
