If I start a sphere on the edge of the grid, it forms at the grid's origin with the gizmo. It won't move from that location. I've rebooted my computer but it's still the same. Neither the Toggle Lock nor the "x' key are the problem. Any help would be appreciated.
I had a different than the Bezier Float in the Curve Editor. I changed it to Bezier Float and everything seems to work ok. Thanks again for your help.
After your first reply, I went to the Motion panel and looked at the controllers. They were there but triple or quadruple-spaced between lines. In the controller list, Posxyz was the default, but I selected default again and the spacing went away. Still everything was stuck at the center. Then I went into the Curve Editor and made the change and everything worked properly again. Thanks again. Glad you're around to help.
