I've got my desktop background set to change to a random image I selected. However, when the computer sleeps and I log back in, the desktop background is changed to black. If I right click on the background and choose 'next desktop background' it brings up the next image.

I've gone into Ease of Access to make sure the 'remove background' option under see my computer better is NOT checked.

I've verified my Windows IS activated. (These are the two most common solutions regarding a black desktop background.)

Why I can manually rotate to the next background image but it is automatically changing it to black is a mystery.
