Yes, it was in commander mode. Thanks Chris.

Got that part of it solved. (Got to have a check list for shooting pictures) But I can still change the ISO in flash mode with Auto ISO. Like some of you said, you are not suppose to be able to do that in with flash in Auto ISO.

Image is as expected. ISO 100 has dark background. ISO 12,800 has bright background but lots of image noise.

Still suspect Nikon may have made a change in the D7000 camera software recently. Or this camera is acting strange.

Maybe if someone try to load the latest software, they can change ISO in flash also. That would prove there is a change.
