[antlr-interest] ANTLRWorks hiccup?

Excuse if I'm being stupid, too tired, or just plain blind, but
shouldn't this be a valid lexer grammar:
------
lexer grammar Lexer;
START : ID WS+ ID
;
ID : ('a'..'z'|'A'..'Z'|'_') ('a'..'z'|'A'..'Z'|'0'..'9'|'_')*
;
WS : (' ' | '\t' | '\n' | '\r')
;
-----
ANTLRWorks keeps telling me that it can't show the DFA/NFA diagram
for the rules, because there's no start rule to be found.
This is certainly not the case, and ANTLR happily produces a lexer
for me.
Manually deleting the "lexer" part from the first line and then
typing it again fixes the issue?!?
The generated source (by ANTLR) seems to be ok to me...
puzzled,
Kay
