Rich, If you start with the default Mandelbrot with maxit=150, and open the palette editor using 'e', when you scroll around the image with the cursor key you get some palette entries that exceed 255. Theoretically, with maxit=150, you shouldn't see any palette entries that exceed 150. I know, truecolor doesn't care about palettes, but for some features to work, the simulation of a palette has to be accurate. As an aside, to avoid this problem, Xfractint currently doesn't show the palette editor when you are using a truecolor mode. If there is a problem with the getcolor() routine returning a value in the appropriate range, this will also confuse boundary tracing. Jonathan
