A working example of fancytabs

I tried fancytabs by the example given in its manual as

\documentclass{scrbook}
\usepackage{scrpage2}
\usepackage{fancytabs}
\usepackage{lipsum}
\let\oldchapter\chapter
\oldchapter[#1]{#2}}
% Set central right header to display tab
% for both scrplain and scrheadings

\renewcommand*{\chapterpagestyle}{scrplain}
\begin{document}
\chapter{A chapter}
\lipsum
\lipsum
\end{document}


but it does not show the vertical lab displayed in the manual document or HERE. I just copied the exact example from manual. Where did I do wrong?

You have to compile twice. –  Marco Daniel Apr 19 '12 at 18:27

The package fancytabs uses the package TikZ to draw the tabs. To compute the correct position of the tabs TikZ needs two compilation runs of (pdf)latex.
