[ODE] dBodyAddForce & dBodyAddForceAtRelPos

[Jeroen van den Belt]

I try to represent chess pieces by two different primitives:

1. CappedCylinders
2. Boxes

When I apply dBodyAddForce & dBodyAddForceAtRelPos to let fall a piece, the
piece represented by a Box will move, but the pieces represented by
CappedCylinders don't move at all.

I tried to lower and rasing the forces but nothing is happening with the
cylinders.

Any clue?
