IK on arms problem

Hi all,

I'm having a problem with a rig I built for my robot character. The arms are using IK, but for some strange reason when I keyframe the goal nulls, the bones jump away from the goal like in the attached image. When I select the goal null and move it slightly, the bones jump back into position.
It is straight forward IK...nothing flashy. "Full-time IK" is on, and that is all. The shoulder bone has "Unaffected by IK of Descendants" ticked.

The rig started to behave funny after I parented the object to a "Master Null" to be able to move everything together. But even after changing it back the jumping of bones still takes place.

Any ideas?
