Groupy has stopped functioning as normal recently, the "When should Groupy combine windows" settings no longer work. The only functioning setting is the default "always group on top of each other." I would prefer to use the right click setting but and both shift and control don't work and when moving windows over each other there is no colour indicator to highlight that windows will combine.
EDIT: While writing this thread I was testing the problem which resolved itself for the space of 5 minutes, it has now returned. Open windows are Steam, Chrome, Directory Opus.
