Not able to Rotate things in object mode (camera, mesh)

I’m using blender 2.59.
I’m not able to rotate my camera, the figure I’m sculpting, or the lights in object mode. I can rotate things in edit mode, such as parts of the mesh.

I know there’s an easy solution to this problem, I just can’t for the life of me recall what I did wrong.

What do I do to fix this?

Edit: It is only occurring in this one scene.

Turn off Manipulate Center Points in the header.


OH WOW thanks… so frustrating that was.
