Not totally sure if this is a Firefox issue only. Occationally, I see
issues closing the Manage Queries or Purge Manager popup windows. It
throws an error message and the popup window cannot be closed. Keeps
repeating the same message in a Javascript alert. You cannot even
minimize the popup window. The only recourse is to kill the browser and
relaunch. Anyone see this. Minor but annoying. 9.1 M020
