Armature problems

Alright, I’m making a new model and I wanted to try armatures, for 2.5.

This is the rest position.


This is what happens when I rotate any bone.


See how the arm goes another 40 or so degrees than the actually bone. Does anyone know how to fix this?

TY,
Robert

p.s. I’ve also made sure which areas have been weight painted, 100% on the arm and such.

open up the dope sheet and check to see if you have keyframes on the mesh. if you have delete them.
