Problem addin' RigidBody

[ben]

Hi everyone, and thanks for your wonderfull work.
I've just discovered the rigid branch and really apreciate this (as
long as I won't have to create multiple constraints...)
but as I get the last svn, I cant help make it interact with the group
it's placed in ???

example :
_world is my group, any other kind of particles run just fine, but
when i add :

var rect:RigidRectangle;
rect = new RigidRectangle(280, 80, 40,20,20,false, etc...);
rect.setDisplay ( new Bidle(1, 0.5));
_world.addParticle ( rect );

the rect appear in my world but doesn't interact with the others ???
Did I missed something ????

As I've just discovered, it seems that Rigid Particles and regular
Particles can't collide together !
Is it an old "souvenir" or is it still true (as it seems in the rigid
branch svn) ????
