Wrong blank sides on twosided memoir - discontinuity in odd and even pages

Question

I'm preparing my thesis using the memoir class and the twoside option:

\documentclass[a4paper,11pt,twoside,openright]{memoir}

I have parts and chapters, and a blank page is always inserted after a new Part page. However the blank page seems to mess up the continuity between even and odd pages. This means that when I went to print a copy of document the other day some whole parts have the page numbers on the wrong side.

I also have some figures which extend into the margin and if I'd bound what I'd printed these would have been eaten by the binding rather than being on the outside of the page as intended.

An example of what's happening is below:

Last page of preamble      - odd page (right of spine), number vii
Part title page            - even page, number 1
Blank page                 - odd page, no number
First page of new chapter  - even page, number 3
Next page of chapter       - odd page, number 4, page number and
                                          header printed on wrong side

I have the following in my preamble which might be relevant:

\fancyhead{} % clear current definitions
\fancyfoot{}
\fancyhead[LE]{{\scshape \leftmark}}
\fancyhead[RO]{{\itshape \rightmark}}
\fancyfoot[LE,RO]{\thepage}

And this:

\begin{document}
\input{./title.tex}
\pagenumbering{roman}\setcounter{page}{1}
\newpage
\begin{abstract}blah\end{abstract}
\newpage
\begin{acknowledgments}blah\end{acknowledgments}
\newpage
\tableofcontent*
\newpage
\listoffigures
\newpage
\pagenumbering{arabic}\setcounter{page}{1}
\include{introduction}

Anyone know what's going wrong? As it stands I can't just print and bind, and the issue can't be solved by just adding blank sheets of paper in certain places before binding.

Answer 1

\newpage
\pagenumbering{arabic}\setcounter{page}{1}

is inherently unsafe as if the current page is odd you will get two odd pages, so when printed all pages will be on the wrong side of a two page spread. \cleardoublepage would be safer that \newpage here.
