Issue with autocal resetting WB

Hi Tom,

Hoping you can help with this. So I've painstakingly calibrated the W/B and gamma on my Panasonic VT30, through a Radiance XS3D. When I come to autocal the 125 gamut, I select the top option to reset colour matrix calibration settings only and check just the Advanced Colour Gamut check box, however when I click the start button, the software resets the W/B and gamma too. I've done a number of re-installs following your post above, including a complete uninstall using 3rd party software that attacks it all the way to the registry. Each time however, I get the same result. I've included post manual calibration report and capture of the autocal figures. Am I doing something wrong?

Post manual calibration image attached.

Figures from after I click the start button for autocal below:

Quite interested in your answer Paul.

A workaround occurred to me that I may implement as a backup and that is saving the tweaked WB/Gamma data in another (or multiple) CMS memories and copy it back after autocal if need be but like I said, I'm quite interested in the answer to your issue too.
