Just set up a new machine, running windows 10, and installed TortoiseSVN 1.9.4, Build 27285 - 64 Bit
Did plenty of reboots, needed the first one for the icons to appear. However it seems to be stuck in non-recursive mode. The icons are all there, working correctly, but when I click on a parent folder, it says there's nothing to commit. If I drill down to the child-most folder, and try to commit, it seems to figure out what files to commit. It's just a pain in the butt to have to drill down to every folder just to get the committing working, seems broken to me, or is there some setting for this?
