Every once in a while, when doing a Bible search (I rarely do others so I don't know if it's limited or not), when I type a new search parameter into the box, after I press <Enter> it disappears and the last search terms comes back. Sometimes it will work if I pick the word that shows up in the dropdown that appears, and sometimes that doesn't work either. It seems like this is a bug, but maybe I'm doing something wrong? I am on 4.2a SR-5 (4.21.5.0959).
