Soft-proofing has had a weird behavior for a while now. I'll have several images selected, and I want to make soft-proofed adjustments for each. So I'll click on the first one, hit S for soft-proofing. Then when it shows soft-proofing mode, I'll make my first adjustment, to exposure or whatnot - and then it creates the virtual copy, which is expected. What's not expected is that this takes a few moments, then right after the soft-proof VC is created, it auto-advances to the next selected photo! So then I have to go back to the VC of the one I was trying to work on, then I can make make all my adjustments.
