Error: Invalid verify parameters.

Hi, While testing, i cam across "Invalid verify parameters" error. see attached screenshot and below to reproduce and behavior after fail. Tested on: Firefox 36.0.1, windows 7 64bit To reproduce: Type bunch of "???????" in the text area in pop up dialog. Behavior after failure is all or combination of following: - Entering right text does not work. - Refresh/audio button do not work. help button is fine. - "Verify" button disables. - Closing the verification pop up, new pop up does not show up. It seems only way to revive the widget is to reload the page. Please let me know if you need more information.
