I can't explain it Tony. I get almost the same URL as you, but without the last "s". However I also tried it with that extra "s" and it made no difference.
I don't know how to get the beta version here, and I am a bit afraid to try to get it, because then I may not be able to get rid if it!
Do you know if that beta version is the original beta, before the current site we have been using, or is it the beta of a new site? It would be strange for a new site to have fewer words, unless they were trying to purge old words no longer used, perhaps for the mobile version of dic dot com. Who knows?
