Walk animation issue - flailing arms

Hey, I am using qAvimator to try to make a walk animation for an attaching ridable (a horse, to be specific). I have the arms locked in a position that should hold the reins, but when I walk with the animation on, the arms move rather a lot, like they are trying to be taken over by the default SL arm swing. I have the priority at 4... what is causing this?

Thanks,
Valdyr

Did you move every joint in frame 2 of your anim. If not then for some reason the priority of the anim does not take effect on those parts not moved and they tend to continue with sl anims

i tend to move every limb/joint in frame 2 then set frame 3 back to the standard t pose before starting my anims. this seems to cure the problem
