New user (2.59) question: Apply pose as rest pose

I rigged my figure following a 2.4 tutorial (I’m now in 2.59) and I don’t claim to fully understand why it works so well, but it does. I have had no problems posing the figure. I notice that the leg bones are yellow, unlike the others, but I don’t know what that signifies.

Now, however, I want to apply the pose as the rest pose and when I do, those yellow leg bones shift their position slightly, obviously not good. (see attached JPG)

Is there something I can do to prevent that? Thanks for any clues

It might be those bones were keyframed. Press Alt+R and perhaps Alt+G to see if it snaps back.

I believe the yellow colour indicates that they have an Inverse Kinematics bone constraint active on them.
