Hi, I am having a Dell laptop with Windows XP. After a long time today I thought to change the wallpaper of my desktop. Hence I selected a picture from my folder and right clicked to set it as desktop background. It fails. I am not able to set any picture as desktop background. I went to Desktop Properties and tried setting from there but still the same problem. I am able to change the color from these option but not able to set a background picture. Any idea what has went wrong and how can I fix this?
