Silly 2.36 bug! In FaceSelect mode, other solid objects didn't show. Bad! Additional; when using Halo material, and setting 'X Alpha', and disabling Halo option, the 'Only Shadow' option turned on... uses same bit... No time for real fix here, so for now the bit is always cleared after disabling Halo.
