I bring up the raw refine screen for a particular image (snap 1 below), click on the White Balance Dropper, hover over patch 10 on the gray scale at the bottom of the image (which is pretty close to neutral already:131,132,129), and click the dropper. The white balance is adjusted, but gives the result shown in snap 2 below. This happens on two different computers running QU v2014.250 and several different RAW files tested.
OK I think we have a handle on it, now.
It took me a while to find a couple of Raw Fuji S9000 image to download.
I got some finally.
They all turn green when trying to do a WB in refine.DCRAW did not cover that camera including all the features of the Raw.
You can still do any White Balance in the Editor screen.
