Re: continued troubles migrating from 1.6.1

I will try doing a fake registerEnvironment() for now... I still have no
idea what is going wrong.

I'm using MacOS and CodeWarrior. The source files are all in my CodeWarrior
project, so the classpath should not matter. The classes should all be
linked into my application's jar file. If I use the project browser I can
see the kawa.standard.Scheme class and the registerEnvironment method on it.
Also there is a tool called ClassWrangler that disassembles .jar files, and
the class and method are in there.

This seems to be a development-environment-specific issue so I won't bother
this list with it any more... thanks for the suggestions. I've also posted
some questions to a codewarrior news group in the hopes that they will have
some suggestions.
