Thx, Chavfister and NextDesign.
I'm working in version 2012. I've managed to get a better rig after trying and trying and trying ;-) I guess there where some rotations values, so Freeze transformations did help to solve the separation of the bones from the character, but my bending isn't good at certain points. Still need to learn a lot here. Basics of rigging is easy, getting a good rig, that's another thing...
