Sometimes it seems that nothing happens with Mail Archiver. In the Force Quit Applications window you can see the following:

This may happen during

  • Opening an archive when updating to a new version.
  • Opening an archive after a crash.
  • Diagnosing an archive.

The database behind Mail Archiver is busy working. What is the absolutely worst that you can do now: force quit Mail Archiver. If you do this you WILL leave the database of Mail Archiver in a not-happy state. And it's 100% guaranteed that when you now start Mail Archiver again the opening of this archive will take a long time (again).

When the "not reponding" happens during archiving and you don't see the progress bar moving for longer than 30 minutes THEN Mail Archiver has a hang. In the last years this occurred very very seldom.
