For what it's worth.. i tried to apply this patch to my standard 0.5 
version in my Minas Tirith demo, and this modification:

//Dist= Radius - Dist;
Dist= Radius - side; // (mg) penetration depth is distance along normal 
not shortest distance

Make all my spheres bounce like hell ( and never come at a rest ) on 
flat triangles..

I'll stay with the stable version for now.
