Martin, sorry to bug you but ...
I'm afraid that since yesterday (or earlier? I don't come in here every day, since not much is ever happening yet) the dictionary search is no longer working for me in en-es, on the iPad Mini. Nothing has changed anywhere else that I can see, but here I currently only get a 500 server error.
500 Internal Server Error
I had one funny search result one time a few days ago that I wish I had thought to copy. The URL randomly added some garbage characters, of which I remember mainly ...%2525%2525%2525...., I think at least three or four times, and then something else short at the end.
I've tried entering the en-es realm by different methods, whether via my bookmarked link (I did remove the old version with 'beta' in it, I think) or via the other dicts and the flag icons, but it doesn't seem to matter. I've also logged in and out and started over, I think; ditto.
I did also notice that the two-flag icon seemed to be moving again after being clicked on, rather than staying anchored at the rightmost end in position 7 of 7 language combinations, where I personally find it easier to remember.
Not sure if any of this is any help, but it does seem Iike the dict needs to work. /-:
