Just bought the app from the iTunes store. When I add a new item, the save button at the top isn't available. The item is there if I re-enter the app from the main iPhone menu. When I edit an existing item, there is no option to save, just to cancel. I have to return to the main iPhone menu and re-enter the app. There is no way to return to the main menu from inside the application itself. Am I doing something wrong here?
