If you know what you are doing, go into the CR2 file with a text editor and find these lines for each leg;s IK chain:-

        inkyChain     rightLeg  
                {
                on
                name Right Leg

and replace "leg" by "legg" (and replace the "on" by "off"). That will stop all that stupid automatically setting the legs IK-on, for that model. That annoying mechanism also IK-parents the feet to the character's BODY. That is why the feet stick to the ground when you move his hip but not when you move his BODY. His BODY is an invisible part which is parent to his root segment.
