Ahha, some more bad coding from me.
Argh.
Replace BoxVisibility in DXObjectUtil.cpp (starts on line 126) with this:
int __fastcall BoxVisibility(TDXPoint Point,TDXVector Front,TDXBoundingBox*
Box,
 float AngleViewed,float MaxViewRange) {
    //Check Center
 TDXPoint Pointing = Box->Center;
    Pointing = Pointing - Point;
    if(TDXVector(Pointing).LengthNS()>MaxViewRange*MaxViewRange)
     return OUT_VIEW;
    float Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
  return IN_VIEW;
 //Check 8 corners
 Pointing = Box->Center +
TDXPoint(-Box->LengthX,-Box->LengthY,-Box->LengthZ)*Box->World;
    Pointing = Pointing - Point;
    Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
  return PART_VIEW;
 Pointing = Box->Center +
TDXPoint(-Box->LengthX,-Box->LengthY,Box->LengthZ)*Box->World;
    Pointing = Pointing - Point;
    Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
  return PART_VIEW;
 Pointing = Box->Center +
TDXPoint(-Box->LengthX,Box->LengthY,-Box->LengthZ)*Box->World;
    Pointing = Pointing - Point;
    Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
  return PART_VIEW;
 Pointing = Box->Center +
TDXPoint(-Box->LengthX,Box->LengthY,Box->LengthZ)*Box->World;
    Pointing = Pointing - Point;
    Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
 Pointing = Box->Center +
TDXPoint(Box->LengthX,-Box->LengthY,-Box->LengthZ)*Box->World;
    Pointing = Pointing - Point;
    Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
  return PART_VIEW;
 Pointing = Box->Center +
TDXPoint(Box->LengthX,-Box->LengthY,Box->LengthZ)*Box->World;
    Pointing = Pointing - Point;
    Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
  return PART_VIEW;
 Pointing = Box->Center +
TDXPoint(Box->LengthX,Box->LengthY,-Box->LengthZ)*Box->World;
    Pointing = Pointing - Point;
    Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
  return PART_VIEW;
 Pointing = Box->Center +
TDXPoint(Box->LengthX,Box->LengthY,Box->LengthZ)*Box->World;
    Pointing = Pointing - Point;
    Angle = TDXVector(Pointing) ^ Front;
    if(Angle<0) Angle = -Angle;
    if(Angle<=AngleViewed)
  return PART_VIEW;
    //After all this it's outside
 return OUT_VIEW;
}

Note: if it still doesn't work reply and I'll give you the DXMath units to
try to fix it again. :-(
