Adding

@comment = FXTextField.new(commentframe, 60, nil, 0,
    TEXTFIELD_NORMAL|LAYOUT_FILL_X)
@comment.connect(SEL_KEYPRESS) { |sender, sel, event|
	if (event.code == KEY_Return) || (event.code == KEY_KP_Enter)
		# User clicked the Enter key; save this event message and then
		# return 1 from this handler to let FOX know that we've handled
		# the event.
		unless @comment.text.empty?
			addevent
		end
		return 1
	else
		# It wasn't the Enter key, so we return 0 to let FOX know that
		# we didn't handle this event and we want the text field to
		# it like it usually would...
		return 0
	end
}

gives:

lizzy:~% ./fxev.rb 
/usr/local/lib/ruby/site_ruby/1.6/fox/responder2.rb:29:in `call': return from proc-closure (LocalJumpError)
        from /usr/local/lib/ruby/site_ruby/1.6/fox/responder2.rb:29:in `onHandleMsg'
        from ./fxev.rb:260:in `run'
        from ./fxev.rb:260

OK, I'll have a look :)
