and the jod went into a dead loop. Any idea about it:

WARNING - G4Navigator::ComputeStep()
          Track stuck, not moving for 10 steps
          in volume -world- at point (3.176821685,6.558946445,-48.75)
          direction: (-0.3019686021,-0.9533178484,0.0002078964686).
          Potential geometry or navigation problem !
          Trying pushing it of 9e-10 mm ...
