Facebook recently made some changes to their service that affected the Facebook uploaders in Sparkbooth. Sparkbooth 3.4.28 addresses these changes which include:
- Clear previous Facebook session for "Guest Facebook" uploader. So the previous guest's email is no longer displayed on the sign in screen.
- Fix "Malformed access token" error when signing into Facebook.
- Fix saving of max guest print setting
- Prevent application minimize when locked
