Glad you figured it out. Here's an ice pack.

For those who haven't yet, Inverse Kinematics (or IK) can be turned on and off from the Figure menu. When it's turned on, you can move the paws, and the rest of the limb will follow automatically. Without IK, you have to pose each part of the limb separately.

The only corrected Dedicated Digital .cr2 that I know of is for the orangutan, which fixes head movement and improves bending. It's by Scott Ayers, and can be found on his site, Pixelatious Creations.

TBKoen did a remapped version of the Dedicated Digital T-Rex, and the .zip archive includes a new .cr2, but as far as I know it's just a remap, and doesn't fix anything else. It's also rather difficult to track down.
