A recent AVG and Avast antivirus update is preventing DisplayFusion 9.9 from launching on some systems. If you're running into this issue, please update to the latest DisplayFusion 10.0 Beta.
The Automatic setting for Grouping is just to detect the setting based on what the Windows taskbar is set to. However, DisplayFusion doesn't yet support the Group When Full option. We do still have an open feature request for it though, so I'll definitely post an update when it's available.
