I then installed TeXLive 2011 and it again worked perfectly. My guess is that something on your system is interfering. Maybe you have an old version of some package in your personal tex tree that is being used. Take a look at your log file; it should show you the versions of each package that are being used to typeset your document. For instance, for enumitem, mine says: (/usr/local/texlive/2011/texmf-dist/tex/latex/enumitem/enumitem.sty Package: enumitem 2009/05/18 v2.2 Customized lists \enit@toks=\toks24 \labelindent=\skip48 \enit@outerparindent=\dimen138 \enitdp@desc=\count130
you TeXLive is not up-to-date! enumitem is if version 3.5.2 Herbert
