Hi Norbert,
you may want to put one of your app names {seaside. magritte. magma} and
one of the class names into google search. The search result connects you
immediately to the collective knowledge of the Squeak community, example:
- http://www.google.com/search?q=weakarray+seaside
Besides of that, you can look for class references and find the guilty who
send #new or #new: to one of the classes.
