Armature's Not Fully Connected to Mesh? Back again, I did some repainting the weights on my simple knight here. Previously he didn't have this problem. I had to subtract some weights off the chest which were pulling strangely but the arms seem partially detached from the mesh? I need a picture to describe it, because again, I cannot articulate it properly to let Google answer this question... which is probably ridiculously easy. 



And I attached my blend file for ease.


Thank you.
The problem is that the 'Spine' is  also affecting the head and the arms. If you remove the arms and head from this vertex group, it works just fine.

In weight paint mode choose the 'Spine' vertex group. Use the subtract brush to remove the weights from the arms and head. Then test with different poses and adjust the weights where needed.

Here is a screenshot of how it should look like (although some more tweaking is needed :) ):
