This seems now be fixed with the most recent Mac OS X bug - it now again works for me. We had a bug report earlier here (one year ago), where I couldn't reproduce it. https://savannah.gnu.org/bugs/index.php?26261 I strongly suspect that this bug was introduced into Mac OS X about one year ago, and my usual update lag back then caused me to mark the problem as "works for me" back then. -- Bernd Paysan "If you want it done right, you have to do it yourself" http://www.jwdt.com/~paysan/
