--- Comment #22 from Johannes Obermayr johannesobermayr@gmx.de 2012-04-26 12:23:39 CDT --- With current Git snapshot I can install ElsterFormular-10.4.0.0.exe again.
The remaining issue is that clicking in a field opens a new window to display the help instead of display the context help in the yellow box at the bottom.
