I've just installed emacs 24 on 12.04 following the instructions here: http://www.mikeyboldt.com/2011/11/30...-24-in-ubuntu/ and though it installs and I can run it from the terminal, I can't get an icon for the app to work in the launchbar. I.e. after the first launch, an icon does appear, but clicking on it doesn't switch me to emacs, nor does an emacs icon show up when switching between applications with alt-tab. Also, after closing down the app, clicking on the icon that was put in the launchbar, doesn't actually launch emacs.

What gives?
