newbie- simple texture/animation distort problem

Trying to learn maya, ive made my model, boned and weighted it, done the uv's.   Applied a texture.  But when i move a IK handle or bone the texture goes crazy.
Is there a simple way to fix this? so it doesnt distort.

I am pretty sure that the UVs are ok. Its hard to say, but seems to me that something so controlling the texture position(projection). Play a bit with that.
hope all this made sense :)
