a Right Click, set as Background before from within a Windows Explorer or My Documents folder.
The only right clicking option I can remember is an image from a web site in Internet Explorer, and selecting "Set as Wallpaper".
Are you sure your method is right?
There is another way to set a desktop background. Open up MSPaint, (Start > All Programs > Accessories > Paint), find and open your image and in the File menu select "Set as Background (centered, or tiled)".
Other than that, I'm not sure what method you mean.
Wondering if anyone can help, im runnin SP2. Lately i have been unable to set a desktop bg from within my folders, by right clickin set as..... i can set them from display option and frm the web. can anyone offer up a solution or tell me whats wrong?
