Hi Thomas,
Thanks for your quick response, here's the version of my ConTeXt,
joshua@msh-pc1983:~$ context  --version

mtx-context     | main context file: /usr/local/texlive/2011/texmf-dist/tex/context/base/context.mkiv
mtx-context     | current version: 2011.05.18 18:04

Best regards,
Zhiguang

Hi All,
The simpleslides can not work any more after texlive 2011 upgrading,

What version of context are your referring to, i.e. what its the output of context --version? texlive 2012 is just around the corner. We had to adapt some code to recent changes in context, so it is indeed possible that this is not backward compatible with older versions. I can only speak for myself, but I don't think that it's worthwhile looking into problems with older versions; texlive 2012 should be released within the next few weeks (maybe Aditya has different opinions on this). So if you need this urgently, best install the context-suite, aka minimals, or wait for TL2012.

All best

Thomas
