Something started last evening I haven't seen before. Upon reboot, when the wallpaper is up and all the icons, the screen will black out the same way when a program is booted up and is not aero compatible. The screen blacks out for a couple seconds, and then comes up ok. Having not done this before, and no programs having been booted up at all, does anyone know why it will do that? Answers & help will be appreciated. Thanks.
