Sometimes exception occurs when gaining focus

• What happened?
  Error pops up:

Press Enter/Escape to Dismiss, or F5 to restart the application.

Problem will persist upon either dismissing or restarting the application.

  Switching to POB from POE.

• What steps will reproduce the bug?
  When POB is minimized on a second monitor and I ALT-TAB into it.

• Does it reproduce every time?
  Problem does not reproduce 100% of the time but is rather frequent.

• Provide a build code:
  Running 1.4.170.24 on Windows 10.

Reproduisez le changement de focus en réduisant POB sur un deuxième moniteur et en utilisant Alt-Tab sous Windows 10. Commencez par la fonction downloadFile de update-thread à l’emplacement indiqué dans la stack trace et cherchez pourquoi outFile est nil. Le travail est terminé lorsque le changement de focus ne déclenche plus l’exception et que l’application reste utilisable après avoir fermé ou redémarré.
