[antlr-interest] unable to run or debug grammar in antlrworks 1.4 on Windows XP

Very interesting - thanks.  I suppose this could explain why moving some
rules / tokens around fixes the time-out sometimes, as the order it builds
the DFA in will change, and thus how long certain things take to generate.

Matt.
