When i'm trying to select a set of faces in the Ortographic view, and i somehow manage to select only those faces that points to camera. Faces that point vertical are not selecting and i can select them only in perspective view. I already tried to uncheck "based on camera" feature in settings.
Backface culling? I.e. not rendering those faces which face away and therefor they cannot be selected. http://en.wikipedia.org/wiki/Back-face_culling Check under Display > Polygons > Backface Culling
