This has happened to me a number of times. Photoshop CC prevents me from rotating the object, I can still move the camera around but not rotate. I cant even select the 3D object. Ive check and caps lock is not on.
Im using Photoshop CC on and Imac running Mountian Lion.

What object? What else? You need to provide more info and possibly screenshots. It could be choking on textures or something like that...
