limbs keep losing their rigidity

It seems that I keep getting the arms to work only to see that they've lost their rigidity again. It just happened now as I recorded leg movements through dragging. Right now, the right hand can be pushed up into the shoulder making it really short. Usually, the left arm fares better than the left. But right now they both get really skinny when I bend them. One thing I find peculiar is that the r_arm within the the rarm contains an origin whereas the l_arm does not. And I can't delete it. I've attached the puppet. It's an altered version of Dr. Applesmith from the website. If anyone can have a look, I would so much appreciate it. Oops I guess the .puppet extension is not allowed. I changed it to ppt. I don't know what that is but I gave it a shot. I also attached the .psd file.
