Thanks for your advice to try the Miktex list. I did that, and got the following helpful reply, which fixes the problem for me. best wishes, David You are in luck. That's "only" a enumitem bug. enumitem uses \@enumctr in the argument of an \@ifundefined command. But as \@enumctr is not defined in an (unnumbered) itemize list you get an error. I have sent a bug report to the author. Try \makeatletter \providecommand\@enumctr{} \makeatother until enumitem is updated. Btw: The newest enumitem has changed quite a lot internals. Most importantly it no longer uses the standard \define@key and \setkeys command from (x)keyval (to avoid compability problems with xkeyval). As powerdot uses xkeyval, defines some additional keys for enumitem and does a lot of key settings it is quite possible that this changes will break something.
