I avoid using the Interpreter of ANTLRWorks. 

It does not seem to properly conform to the meta-semantics of ANTLR
grammars. I believe this inadequacy is a known issue/bug. 

as an aside I generally avoid ANTLRWorks altogether as, for me, it just
gets in the way....

Have you tried the Debugger from within ANTLRWorks?

Have you tried just using the command line interface? 

Hope this helps...

(ps: have you tried, from the command line, to Tool, compile, and run
the grammar + test-driver combination that I posted?)
