Why isn't the desktop wallpaper appearing?
In some cases, saving a fractal as desktop wallpaper may not automatically update the desktop.
If this happens, do the following to manually set the wallpaper:
1) Open the control panel Display Properties applet's Background tab.
2) Under Wallpaper, select Fxwallpaper.
3) Set the Display to either Tile or Center.
4) Click OK.
