Negative visibilities at the edge of the bands 
Question: "For some channels from the beginning of the band,
I get visibility values far away from where we would expect them and in many
cases they have negative values​​. What is happening?"

Answer: The strange visibilities are usually at the very beginning of the K band, where there is some contamination by the H band (meaning that the fringe pattern given by the P2VM cannot be reliable). You should restrict your domain to a smaller wavelength range. Checking the P2VM with amdlibShowP2VM would be a good idea to see the possible overlap.

Invisible selection for the color of the file browser 
If you do not see any changes after some clicks into the filechoosers, some users get a better display using a different color map.
cp .../yorick/g/heat.gp $HOME/.gist/gray.gp
After this change, the selected files should be underlined or with a different background color.
