Hi

I can't figure out how to add a space (say 3em) after the Exercise environment . I don't want to do it manually for every exercise, but automatically, by using \addtolength or redefining the environment or something.

For leaving some space in front of it I managed to come up with this:

\renewcommand{\ExerciseHeader}{\vskip 3em\centerline{\textbf{\large\smallpencil
\ExerciseHeaderNB\ExerciseHeaderTitle%
\ExerciseHeaderDifficulty\ExerciseHeaderOrigin\medskip}}}

Thanks.
