I assume there's a subject in the foreground you want illuminated with the flash?

The light output from the flash falls off with the square of the distance. An object twice as far from the camera only receives a quarter as much light. If you want your foreground subject illuminated then the background won't get much light. In order to get both the foreground and background illuminated the same, turn off the flash. This will probably require you to put the camera on a tripod or other stable support.

You might also want to consider using the Night mode. This mode uses a slow shutter speed to allow the background to illuminate, then fires the flash to illuminate the subject. See http://resources.kodak.com/support/shtml/en/manuals/urg00206/urg00206c2s3.shtml

Raise the flash with your fingers. See page 142 of http://gdlp01.c-wss.com/gds/0/0300008700/01/pssx50hs-cug-en.pdf

On a Windows 7 system, right-click on a blank area of the sceen, click on Personalise at bottom of menu and select whatever theme or picture you want as the background. It is slightly different for other windows system, but you should start with right-clicking on a blank part of the screen..

It's the Inverse Square Law. Light drops off as the square of the distance. If an object is twice as far from the light source it only receives a quarter as much light. So, if the subject is lit properly then the background will be dark.

This is a law of physics. However, there are several things you can do about this. One is to move the light source. Another is to have more than one. The D80 can control other flashes, so you can use the D80's pop-up flash to light the subject and the SB-600 (or more than one of them) to light the background. Another possibility is to bounce the flash off a white ceiling or wall to soften and diffuse the light. Another is to use slow-sync, leaving the shutter open longer to let the background illuminate. You can read more about this in the manual.

Short answer: Press up/down while viewing the picture to cycle through the different views of the picture.

Long answer: You're seeing "blown highlights." The blinking areas are places in the picture where you've overexposed and lost all detail. Those areas are blown out to pure white, without any shading whatsoever. That's not necessarily an error, especially if your subjects are inside the house and you don't really care what's outside. In other cases, you may want to reduce the exposure so as to bring up at least some of the details in the highlights. It's generally considered more acceptable to lose details in the shadows, losing things to pure black, than to lose details in the highlights, losing things to pure white.

As I said earlier, losing details in the highlights is not necessarily an error. The camera is merely warning you, pointing out a potential problem.

In the viewfinder?

If you're looking at a  picture review, then you're seeing the highlights. Just press up/down on the multiselector until you find the view you like.

So, the problem doesn't seem to be the flash if the actual subject in the foreground is exposed properly. My guess is that the background is being lit by another light source. Typically, your camera uses a flash for dark areas or what it gauges as a dark area. This doesn't adjust the background for additional light sources. For example, if you're standing outside and there's a tree covering someone that you're taking a picture of your flash will adjust to "properly" light that individual. However, because the flash was used for the main subject, the background is actually now overexposed. The overexposed background will show up as a brightly lit area because the camera had to adjust for the foreground. This will actually reverse itself when it's dark out - meaning if the background and foreground are dark, the flash will expose the foreground, but the background will be black. Hopefully, that helps you understand lighting and exposure. Now, to fix this problem when shooting, you would need to consider several options - 1. SLR camera with aperture and f-stop settings as well as compensation controls. This will allow you to control every element of the exposure, but you still need to be aware of the lighting behind the "subject" to properly expose your shots. 2. backlighting compensation - common settings on both SLR and point and shoot cameras that makes auto lighting conversions for backlighting and other common lighting issues. Test whatever options are on your camera to see what works best for your specific problem. 3. Photoshop retouching - you may take one shot with your subject exposed properly and a second shot with the background then merge the images together. 4. using a tripod to shoot without using the flash - this may give you the closest exposure to exactly what you see when looking at your subject.
