Problem: eDrawings turning out black, light is locked on model?

can someone tell me why published edrawings have lightsourcelocked on?

The published files show the model black(in the shadow) when shadedin front view(it doesn't matter if the shadow option is selected ornot). There appears to be no lighting option in edrawing; or Ihaven't found it yet. Please advise.

Thanks.SolidworksEdrawings
