Cannot see scene/game in editor after loading a project


I've downloaded the CharacterAnimation sample project and also the 2DPlatForm sample project. When I open either one all I see in Unity is a small camera in the scene tab and a blue background in the game tab. How do I get unity do display for example the first scene? (I can build and run the sample projects).

Thanks in advance for any help.


Double click one of the scene files in the project - they're the ones with the unity logo as an icon, and an extension of .unity3d if you're looking for them outside of unity
