This may have been discussed already but I installed the 9-15-2017 DB and noticed the VFB behavior with the scroll wheel has changed. When I zoom in to investigate my rendering, see how details are rendering, I can't scroll out with the scroll wheel. It just moves the image up or down. I have to use the magnifying glasses to zoom out. Is this how the VFB is functioning now? If so, is there a way to change the zoom in/out back to the middle scroll wheel? It's a minor thing but I've already found it cumbersome to view my image while it's rendering. Part of me thinks this is a bug though. It isn't always functioning this way, it's very odd.
