After an random period of time (typically overnight) the desktop wallpaper will disappear and all I have is a blue background. To bring the image back I have to go to the Desktop tab, select a different wallpaper and then reselect the desired wallpaper. I have ran several scans of Symantec Antivirus, Malwarebytes, Spybot, hijackthis, roguefix and Sophos Anti Root Kit. All come back clean. WTF? I have three other computers at work that are showing the same symptoms. Apparently my Google-Fu is weak. I thought this would be a quick search of Google with a fix but have come up empty. Thoughts? Suggestions?
