Hi Marty,
      This is probably my fault. When the new 3D trajectory feature is added,  
the 3D vector is also becoming available to the user. When the vertical 
velocity is omega, it should do some calculation to the convert to w. In order 
to make situation simple, I will check the configuration to make sure  3D 
vector option is disable when there is only omega.
