Has anyone noticed a tendency of Basic Panel's Auto adjustments to push the histogram way to the right (over-exposure)? I was touching up a catalog this weekend and had to override exposure far more than usual. It is possible that I just ran into an usual sample of tricky photos. Next time I run into this, I will try switching processing to the LR3 engine.
Also, I find the adjustment brush's selection/desection functionality gets messed up if you switch between multiple layers. It starts selecting/deselecting in big "blocks". The workaround is to toggle "Show Selected Mask Overlay".
