Seem to have fixed problem with Mac failing to launch when started from Finder.  For some reason, a parameter that begins with '-psn_' followed by a number is passed to the wb_view which does not recognized it and then exits.  Because wb_view is started from the Finder, the error messge is never seen by the user.  http://stackoverflow.com/questions/10242115/os-x-strange-psn-command-line-parameter-when-launched-from-finder
