In all the tutorials I have found for Blender, they assume that the box select tool (pressing B and left-click-dragging a box around vertices) also selects the vertices behind the visible vertices. I am using Blender 2.37 and it doesn't do that. The box select only selects the visible vertices. Is this a functionality change from earlier versions of Blender or is there a setting I have to change somewhere? I'm currently working my way through the Blender documentation, so I may find the answer in there.
