Interesting, thanks. Never heard of that option, and voila it IS on. Turned it off.
Disabled DeskScapes
Background still changing. Interesting now it's changing every 10 seconds and using two pictures in the Stardock folder, NOT my folders.
Ok, going back to Shuffle option...
No way to turn off the background stuff. Turned off 'shuffle' but it still changes the picture every xx seconds.
This time I used a solid colour.
Looks like DeskScapes did indeed turn off.
Many thanks for the pointer. Now back to my WindowFX Beta testing.
