Jeff,

Just a SWAG, but could it be that you do something like

myClasslib=fullpath +name of classlib
set classlib to &myClasslib

Is it possible that you use the full path somethere? Say, in include file?
Check whole project (for instance, you can use Houston utility) for the string with path of your classlib.
