Can we have an interval run during inMenuMode ()?
OnUpdate () runs only when in the game.

http://www.creationkit.com/OnUpdate_-_Form can still be called in MenuMode, although it won't be called natively. You might be able to use http://www.creationkit.com/WaitMenuMode_-_Utility to measure the time delay and call the OnUpdate event manually from elsewhere.
