Yes, Ron, both Fujis have the latest firmware. And I've found that the greyed out sliders occur on all images shot with the X100T on June 6th only. I'm at a loss to point my finger towards the camera, LR or DNG format. But 263 images, all with the same greyed out sliders when converted to b/w point towards a real issue, not just a one-off goofy image.
A shame this can't be repeated (yet), I'd like to know exactly which settings or environment causes this strange behavior.
