Dimage A2 image problem

I have a new Dimage A2 digital camera. I am seeing a weird problem on my images that I would like to know how to correct if possible. Another Dimage A2 owner that I know has not experienced the same problem. I have been taking pictures in the Auto setting on Fine quality. In the view finder I am seeing weird color pixels (usually magenta). These pixels tend to show up in highlight areas where there is a gradual change of color. These pixels also show up on the computer and in high quality prints. If I was working on an image on the computer I would think that that I was using too few colors, and that the computer was interpolating the rest. Is something like that happening? I couldn't find anything in the manual about numbers of colors. What might my problem be? Hopefully not the camera! Thanks.

Could you post a sample?

Good idea. Here is one of the most obvious examples. See the purple specs in the sky. Since I have posted, I have looked in the manual and red reviews. I have seen reference to "purple fringe" but no explanation about what it is or how to avoid it.

Purple fringing is a lens issue, this is a sensor/processing issue. Call them as soon as you can, this should NOT be happening.

Thanks! I will contact Konica Minolta.
