28 May 2020 -  second captivity development

Latest Version: weightfield5.16.zip

New to this version:

- The “load” button allows loading a file

- The “save” file allows saving the parameter to a file

- The red “XXX” button means that the directory where you want to save the file does not exist.

- The red “?” button means you are overwriting an existing file
