In WASystemConfiguration you have the following code:

configurations
    ^ configurations copy
        addAll: (WASystemConfiguration allSubclasses
                collect: [:ea | ea localConfiguration])

addAll: returns the argument, not the newer collection.  The effect is 
that I don't see my "user configurations" in my browser.  Is this a 
bug?  Should the method read:

configurations
    ^ configurations copy
        addAll: (WASystemConfiguration allSubclasses
                collect: [:ea | ea localConfiguration]); yourself
