(setq default-cursor-type 'hbar) does not yield the desired cursor-type, at least in Emacs.app. The cursor continues to be a block cursor. In the current Carbon Emacs this works (GNU Emacs 22.2.50.1(i386-apple-darwin9.4.0, Carbon Version 1.6.0) of 2008-07-16 on seijiz.local). (What I would really like is a horizontal line cursor (not a bar or box), but I don't see how to get that either in the current Emacs.app or Carbon Emacs.) Gil No crash.
