Ah... I found the problem in my test program.
When using this ssg func:

int  ssgIsect ( ssgBranch *root, sgSphere*s,sgMat4 m, ssgHit =20
**results ) ;

the relative position of intersector and intersectee can be
in either the inverse mat for the root, or in the 'center'
member data of the sphere.

I had put the sphere pos both in the inverse-math *and* in
the sphere itself -> incorrect results.
