I had 2 GUIs(UIRoot) in the scene. When the scene loads, one will be turned off(Multiplayer Menu), the other will stay on(Main Menu). When user clicks "multiplayer button" the MainMenu and all its children will be active=false and the Multiplayer Menu will be active=true.
This used to work in 2.08, but now, even when one of the GUIs is not active, it is still visible, I can't turn it off!
