There is one ''Anagrams'' cardbox for each lexicon, and the contents won’t automatically be brought forward when you begin to study a new one. Currently, NZM has no mechanism for importing cardbox/quiz-statistics data, so, here are a couple of ways to do it, both involving Dropbox sync. One is to use NZ’s ''Cardbox'' tab to target the new lexicon and use the ''Import…'' button to merge the old lexicon’s data into the new lexicon’s database, then sync everything back to your mobile device. The other, which doesn’t require NZ, is to go to '''<tt>dropbox.com</tt>''' and copy the '''<tt>Anagrams.db</tt>''' file from one lexicon’s subdirectory under '''<tt>Apps/DropboxZyzzyva/quiz/data</tt>''' to the other, then go back to NZM, sync, and create a new cardbox quiz that targets the new lexicon.
