For me mostly everything works great, makros dont produce an wow error for me. I have just the problem that the ingame interface gets blocked every time and i cant changes breast items like robes ans such things but it runs without problems.
I noticed, that when i have the weapons on the body and morph them they still keep displayed. When i press the button that my char wears them in the hands and i morph them then, they get morphed without problems =D just want to have said this, maybe it helps to find the bug
