In the plot windows for the drop-down-menu options "CIE XYZ cone-fundamental-based spectral tristimulus values" and "CIE xy cone-fundamental-based chromaticity diagram", the responses of the check-box "Comparison with CIE 1964 10deg" are opposite of what they should be (showing comparison plot when unchecked, and no comparison plot when checked -- this should be the other way around.)
