I have a WPF program that is auto run via an entry in the registry on user login. The program starts with its main window hidden, checks a few things and if the startup conditions are right, makes the main window visible, otherwise the program exits with status code 0. Sometimes when the program runs, windows will present a popup saying that the program is hung, then both the program and the popup disappear. Is there a Windows service that monitors image activation? How do I stop Windows from "overseeing" my program startup?
