It is so far! After processing of my to-do list, longer testing and a few bug-fixes hereby the final version is still finished. I hope that I found all bugs. I still discovered an exception, but this is thrown Java internally. Has something to do with the JTree. This exception has however no influence on the correct program flow and emerges also only very rarely. The final version can be referred under Thesis (diploma): Multimedia algorithms and datastructure assessments (MA&DA)-Download. The work was always joyfulness to me and I would like hereby once again thank for the advertisement and supply of this topic, both by my responsible person Stephan Trahasch and the caring Professor Dr. Thomas Ottmann. Notes: I had begun the work at 13.11.2003 and term for filing was 13.05.2004. In the context of a paid universitary activity I extended these still to 25.11.2004 by a few features.
