Status: Fixed The code to support this was already in place, but did not work because Application.Exit() had been invoked, making all messageboxes return Cancel without showing. I also improved the logic a bit so a cancel does not invoke the cleanup afterwards, making the exit procedure faster. I also added checks for the stop command to the code that fetches the signature files, to make the application respond faster to the stop command. git-svn-id: https://duplicati.googlecode.com/svn/trunk@490 59da171f-624f-0410-aa54-27559c288bec
