[antlr-interest] antlrworks tutorial problem

[Andy Tripp]

I'm just starting to try to use antlrworks, running through the
"expression evaluation tutorial". I'm able to type in "2+3*4"
into the interpreter and that works fine, but when I go to the debugger,
it seems that the input pane is not editable - I can't type into it.
This is on windows, running antlrworks either from a cygwin command line
or just double-clicking on it.
