The memoir class has been recently updated (Dec. 11) and changes have
been made to spacing commands.
As a result, a LyX document using the class will produce errors if
paragraph spacing is defined through the Edit>Paragraph menu.
For example, if your document is one-half spaced, but you'd like to
single space specific content, you will get an "environment undefined"
LateX error.
Furthermore, documents using a custom quote style from the memman.pdf
won't work. For example:
\makeatletter
\renewenvironment{quote}
{\begin{spacing}{1}\list{}{\rightmargin\leftmargin}%
\footnotesize\item\relax}
{\endlist\end{spacing}\noindent\hspace{-0.333em}}
\makeatother
The first problem can be overcome by keeping all paragraphs with default
spacing, and using ERT commands on a separate line, e.g.,
\SingleSpacing \OnehalfSpacing -- but I don't know what do about custom
spacing (say, half a cm) or the custom quote style.
Best,
