Fred or Terry-

I decided to try raw processing ONE MORE TIME (I had never been able to get it to do better than the .jpgs that Canon generates in camera. The white balance isn't quite to my liking, so I do raw refine on a selected image, set the white balance to 2 toward blue, and save. The next time I go into raw refine on the same image, the white balance has been reset to 0, although the other settings I changed, like fill, are still there. Why won't my white balance setting stick? QU 13.103

The WB setting does "stick", it's just that the slider is re-set to zero next time Refine is used. That's the way it works.
If you take a WB setting from the image, the slider does not move at all and that sticks too.
When WB has been set, red lines appear either side of the WB dropper button. See screen shot attached.
Also, if you select and middle mouse button click the thumbnail, raw refine information is displayed with the image.

To check out what I say and convince yourself, set the WB slider to an extreme so the change is very obvious and save. Open refine again, the slider will be zero but the image will the appearance you would expect with the WB way off.
Right click the WB dropper button to clear the setting completely.

There is an Auto WB (AWB) tick box on the refine controls too.

I generally prefer to have my camera set to the appropriate ambient conditions, daylight, cloudy etc., and use the dropper on an image to set WB. In fact I use a mini colour checker card and photograph that to enable  setting WB for a batch of images. If conditions are changeable, I may take several shots of the chart.

Thanks Terry, you even answered my next question. "If the WB slider is reset, how do you get back to where you started if you don't like the change?" Still seems a little strange behaviior, since the fill slider behaves differently. Guess Mike had some logical reason which I haven't figured out.

It does mean that you can have 2 bites at getting a WB somewhere near when it was way off in the original image.
