I just got back from a hike, slurped the pix off my camera to my Mac, and can no longer crop my pix:
The usual shortcut C leaves the cursor as an arrow, not the crossed carpenter's squares.
If I add a crop brick to the adjustments pane, entering numbers there makes no difference.
I can make other adjustments -- e.g. levels -- so it's not like I've got it in quick preview mode.
