I use lyx, which makes some things hard to track down. I had to export to latex to figure this one out.

I have some input files with the questions. I get page 1 blank except for marks when the tex looks like this:
<pre>


\usepackage[box,separateanswersheet,automarks]{automultiplechoice}
\begin{document}
\noindent \input{/.../Exam2/Exam2Questions1.tex}
\onecopy{1}{
\input{/.../Exam2TitlepageRev1.tex}
</pre>


If I remove the \noindent before the \input, the blank page and marks go away.
