Beta 4 : "Tunneling" problem much worse ( solved in RC3 )

This seemed to have been solve in Beta2 thru scripting :

function PlayerClass::onCollision(%srcObj, %dstObj, %srcRef, %dstRef, %time, %normal, %contactCount, %contacts)
{
    %dstclass = %dstObj.class;
	if(!(!strcmp(%dstclass,"Region")||!strcmp(%dstClass,"Foot"))) 
	    echo("collision with " @ %dstClass );
	if(!strcmp(%dstclass,"Wall")||!strcmp(%dstClass,"Block"))
	{
	    %srcObj.setAtRest();
	    %dstObj.setDebugOn(5);
	}
	
}

But now it is much worse. The collision callback is only called when the object is already deep inside a wall. Sometimes creating the "tunneling" efect.

Changing the polygons orientation from cw to ccw or vice versa doens't affect the problem.

IMHO, I beleive that this has something to do with the collision layers. Since I have many overlapped triggers and objects in separate layers, the collision system is wasting time testing for collision between them and is taking too much time to generate the proper collisions.
