All of a sudden (and since the latest Windows 10 update, if that has anything to do with it), dictation with Dragon (13 professional) is not working in Firefox, Thunderbird, and Chrome. Browser navigation commands work, but dictation into search engines, online message boards, creating or replying to e-mails, etc., do not. No words appear, no dictation box appears, nada. What the heck happened, and how can I fix it?

Thank you.
