I'm in the assemble room, I add an object, try to move it with my mouse.  Whichever arrow I grab (x, y, or z) the arrow moves, but the object doesn't.  Does anyone know why?

I can move the object using the motion tab, but that's not realistic for setting up an entire scene.  It does this with everything, objects, lights, terrain.  The indicators move, but the selected object doesn't.  I've restarted, and tried this over and over.

Have I screwed up a setting?
