Oi oi! If I set the Ctype of a particle of BRAY, mousing over it would not display the numerical value in the HUD. I am only able to see the spectra that the number corresponds to. This occurs regardless of the HUD mode used. (e.g. None, simple or advanced.) This will happen at any moment the BRAY particle has its Ctype set to some value. I believe this is a bug.
