I can't get info on it from within TeXShop.  When I click on "locked" I get a pulldown which invites me to unlock (which gets prevented, as described earlier) or to duplicate.  If I duplicate, I get a second window, called <filename>copy, which is also blank.  Can't get info on it, either.  But if I go to Finder and go to the source file
