Display Driver failed and/but Recovered

Some times while running windows, due to some circumstances(need not go deep) forces some programs to quit.

In Windows Vista Desktop is run in a program called Desktop Window Manager(dwm.exe).
When this program is forced to shutdown ,the screen might go blank and recover ,as the process re-initiates again.This is not a bug. or a blunt application crash It can be called as Safe Shutdown of a component/application in order to avoid critical damage to other dependent applications.

Every application has an exception that can never be handled safely while devising it. Such exception are taken care by the environment. In this, the exception has been taken care by windows to restore the application safely.
