[antlr-interest] Getting started with ANTLRWorks: interpreter does not show parse tree

Hello,

This is the first time I am using ANTLRWorks.
When I paste the tutorial "Expr" example into ANTLRWorks 1.2.3,  select the
interpreter and enter an expression (followed by enter) ,  the parse tree
window remains empty.
What could be the cause?
