I have the object selected in Object Mode but the Properties Editor is not showing me any settings/options in order to allow me to add textures, modifiers, materials, etc. It's as if nothing is selected yet the object is selected. Switching back and forth between Object and Edit mode makes no difference. Cycles Render is selected. I'm running version 2.79b. I'm thinking its got to be something simple that I'm just overlooking but for the life of me I can't figure out what the problem is.
