In GNU Emacs 23.1.50.2 (i386-apple-darwin8.11.1, NS apple-appkit-824.48)<br> of 2009-07-30 on Pyrobombus.local<br>Windowing system distributor `Apple&#39;, version 10.3.824<br>configured using `configure  &#39;--with-ns&#39;&#39;<br>

<br>Try this: t e s t C-q 0 RET y o C-a C-k C-y -- this should print test^@yo, go back, kill it all, and yank it. But on my system it only yanks &quot;test&quot; -- the null byte ends it all.<br><br>A quick question on #emacs revealed that some other people had the same problem and all of them were using Emacs.app with the GUI on OSX. One user with a 2009-05-11 version using a GUI reported that it works, but my version from 2009-07-30 does not. Another user with version 23.0.96.1 reported a fail as well.<br>
