I would like to post the code, but it's in total over 2000 lines. That might
be a bit over the top...

By now, I figured out that it might be an incompatibility between ImageJ
versions. I use the jar of ImageJ 1.41 in my building environment. After
changing that to the jar of 1.36 and recompiling everything, the plugin
works on all versions of ImageJ I have on my own computer as it should.

A friend of mine tried out both jars as well, and came to the same
conclusions : the old one runs on ImageJ 1.37 in a Java 4 environment, the
new one gives the class-version error. In a Java 5 environment, it all runs
smooth.

I'm still puzzled as to why the extra class makes such a difference, but as
the problem is solved, I'm already quite satisfied. Thanks again for the
help and tips.

Kind regards
Joris
