Hello Markus and Bernd,
I really appreciate the huge effort it takes for you to translate an English manual for us and I am pleased to say that I have found only one problem.
It seems to be an export problem as the phase "Fehler! Verweisquelle konnte nicht gefunden werde" is written where there should be a chapter reference in the main 2012 manual. The error is on pages 14 and 22.
It is not urgent as I already have good knowledge about these areas, but newer users may find the reference about speed profiling in the main manual to be useful.
