[ODE] newbie joint question

[Piotr Obrzut]

Hi,

   sorry for all these messages but this problem still eats me and i
   didn't figured it out by myself :(

   mine model (it is Cal3d model controled by ODE)
   initial state was: http://mathrick.org/files/initial.JPG, and after
   aplying force to the pelvis bone (actualy to the rigid body which refer
   to dynamic properties of this bone) all model follows this force
   and it should look like that: http://mathrick.org/files/wanted.JPG
   but unfortunately after some time it looks like that:
   http://mathrick.org/files/unwanted.JPG;

   what i should do to preserve mine model from this third (unwanted)
   situation?
