Today we received apologies from Benjamins; they’ve promised to update the electronic version. I’m pleased!
The errors occurred because the editor of Pragmatics and Cognition insists on authors submitting articles in pdf format which he then converts to Word format. Obviously, this mangles the tables, formulae, on so on. Apparently, Benjamins would have been happy to accept LaTeX format which is what we had produced originally. If only the editor had allowed us to the submit the LaTex!
