This is how I solved the problem of the razor.
1- I described the bug on my (this) blog.
2- It rang a bell into Kevin's mind;
3- Kevin recompiled both programs (1-H and 13-C).
It may sound difficult for you, yet recompiling a program is very easy (provided you are the author, it can be a nightmare in other cases!).
The new versions work and produce the desired plots.
I will return on the subject with more articles.
Thank you, Kevin!
