Hello,
This morning i send a bug report with playmaker interface in unity, now i fund a clue.
when i enable "Toggle Breakpoint" on an action, when the game is not maximimzed, there is no problem.
When the game is maximized, the game is not paused, but the FSM is Paused, because my character doesn't react anymore.
and when i manually click on pause, i'm send to the FSM with breakpoint activated on it.
and the console message is:
Invalid editor window HutongGames.PlayMakerEditor.FsmActionWindow
UnityEditor.EditorApplicationLayout:SetPlaymodeLayout()
