Flashing between frames (1 Viewer)

[ds14048]

I am trying to build a futa mod. I am getting frames to load but they are flashing between frames 1 and 2. I have registerHisBodyType(); uncommented.
Is this correct? Or am I missing a frame listener or something completly different?

I think I figured it out. It now stays on the futa frame.
function registerHisBodyType() {
var setBody = lProxy.createProxy(him, "futa");
setBody.addPost(function():void {
updateHisBody();
}, true);
