Problem with Rasters & Density Plots

I'm running Mathematica 3.0, and have just noticed that the Raster, Raster Array, and Density Plot commands return all black graphics, regardless of the color directives I use. I would assume that I'm doing something wrong, but for the fact that the graphics for these topics in my interactive version of the Mathematica book also turn up all black. All other graphics (contour graphics, 3D graphics, etc.) work fine: it's just these that are a problem. I haven't had occasion to use these features since I upgraded (?) my operating system from Win 95 to Win 98 a month ago, so I'm not sure if it's related to that, to Y2K, or some other reason. Any suggestions would be very much appreciated. Kevin Connolly
