The notifications that are causing trouble are ones from another appp / game.
Such as ones from a news app or some other game.
I do not understand how the user who reported this bug to me is having issues but
they seem to be.
They also state that they have installed my app on a ipod touch.
They say that when a notification arrives the app
goes into something like what i would call Application_Inactive or
Application_Background but I cannot reproduce this.
They say the app loses data that is normally saved during Application_Background
The only event i can raise is when the app is playing sound when the notification arrives.
