NewtonBodySetFreezeState freezes everybody

[mfdesigner]

Hi,

I am seeing this behavior below. Could it be a bug in Newton 2.0?

I have two tori attached to a weightless column using corkscrew joints.
Each torus has weight 3 unit and is subject to gravity.
When simulation starts, both falls naturally to the ground along the column.

I allow mouse to interact with the falling torus.
If I detect a mouse click on either of the tori, I freeze its simulation.
However, both tori freeze when I called NewtonBodySetFreezeState
for only one of the torus body.

What could be the problem?

Thanks,
mfdesigner

Source code generaly helps people find the problem rather than a general description.

I think this is a bug in Newton 2.0.

In debugger, I have verified that when the NewtonSetFreezeState is called for one body.
All transform callbacks stop getting called and therefore all other bodies freeze.

However, I did find a work around by setting the MassMatrix of the body I want to freeze to zero and
thus achieve the same effect.

Thanks,
