Hey Guys

Just rigging the arms of a simple block man, ive set up the IK handles as requires (from the shoulder to the wrist) and i'm now setting up pole vestcors located at the eblows using a cortrol curve, the problem is when I select the curve (that is aligned with the elbow joing but moved slightly back) and the the IK handle at the wrist and do a pole vector constraint, my joints jump out of place slightly, anyone know whats causing it and how to get round this??

Cheers
