I can't multi select

Whenever I attempt to use the selection box, it only selects vertex that are visible. For example, if I were looking at a standard cube from the front and used the box selection tool to cover the entire box, it would only select the front four vertex that make up the front face, not the other four. Does anyone else have this issue? How can I fix it? (Blender 5.23 Alpha, using Windows 7)

Deslect

You need to be in edit mode.
