I have a problem with the screen updating not working when using nested
subroutines. i.e.

Sub main()

Application.ScreenUpdating = False
nestedSub
Application.ScreenUpdating = True

End Sub

Sub nestedSub()

Application.ScreenUpdating = False
Code here...
Application.ScreenUpdating = True

End Sub

If I run nestedSub, there is no screen flicker. However if I run main, there
is flickering the whole time (as it calls nestedSub)

How can I get it so that if I run main, it only updates the screen after
ending main, not after running nestedSub and main?

Thanks
