[Paraview-developers] Paraview 3.98 Heatracking problem

[Emiliano Pastorelli]

Hi Aashish,

after some thinking (being my first system shaped this way i'm having to 
get aquainted to the concepts still), I realized that ok, the point at 
which the view is aiming doesn't have to move indeed, and that the all 
problem seems to be due to the position of the object in the screens.

I hope you can figure out what i did wrong in the config file (i bet the 
problem is there somehow).

Best,
H
