So far, when I center the container sprite and rotate it, it appears to first rotate from a 0,0 registration point, instead of from its center. I've tried to changet he sprite's registration point, but so far this hasn't worked/helped. Nothing else has worked to fix this rotation problem.
I must be doing something wrong.
Here's the AS3 (to view, add to first frame of new FLA, 1024X768 stage, color black). Rotation segments below are commented as //ROTATION.:
