Setting the same distance from the top of the page for chapter and index titles
When compiling the following example, you can see that the heading heading "Index" (created by \printindex) has a different vertical position than the first two headings.
Strangely, it gets better when you comment out the line \KOMAoption{open}{right} although the positioning is still different.
What is the reason for this behavior and how can I fix it?
\documentclass{scrreprt}
\KOMAoption{open}{right}
\usepackage{makeidx}
\makeindex
\begin{document}
\chapter{First Test}
\chapter{Second Test}
\index{test}
\printindex
\end{document}

\KOMAoption{open}{right}. – tohecz Mar 29 '12 at 14:57
