Quickmail 0.7.8.1 is available with fixes for attachments not working properly to save or open, shift+F10 not working the first time it is pressed within the app and more logging of what the program is doing behind the scenes if you run with /debug. https://github.com/kellylford/QuickMail/releases/tag/v0.7.8.1

Pending any large issues, this will be the last release for a few days as I transition to a different install technology that will support automatic updating and add additional test coverage with such a change.
