Bone rotated not moved

I have this simple scene. I can not move the upper bone. Only rotated.
Whats wrong???
I use Linux Blender r40272.
Thank in advance.

Select the bone and look in the bones panel, under relations, what is the bone’s parent and is connected checked? If connected is checked, un-check it and now you should be able to move it. If the bone’s parent is the bottom bone, the track to constraint won’t work, it’ll be a cyclic dependency. You can’t have a track to constraint targeting a child bone.


Thank you very very much.
