I've been having trouble throughout the day with my wallpaper changing by time of day. I reviewed the setting on the "Custom" panel - all are set to "Dynamic" (including wall paper setting.)
My wall paper, however, is a solid color. It looks like this setting is overriding the dynamic wallpaper of Natural Desktop. If I tweek the wallpaper in display properties, the sample view on the panel shows the appropriate image, but when I hit "apply" I see a quick flash of the image, then the color overlays on top and the wall paper disappears.
When I first installed the program, the background image was OK. When I deleted a few folders on the desktop, the wallpaper also disappeared, leaving me in the position I am now - a boring wallpaper that doesn't change.
Suggestions? I tried rebooting, and I tried stopping and restarting Natural Desktop. Neither trick worked.
