I have been running Windows 7 quite happily for about a year and I have always used the wallpaper changer feature as I become easily fed up with the same picture. This has worked fine until a couple of days ago when one particular photo in the sequence has become stuck. If I right click on it and select "next desktop background" nothing happens. When I right click and choose Personalise, everything looks as it should - all the pics in my slideshow are ticked and are set to change every hour with the shuffle option turned on. I have tried renaming the folder where the wallpapers are stored and tried to change the wallpaper manually to something else but the picture on the desktop refuses to budge - even though the folder it is in has been renamed, so how is Windows finding it??
It would appear something has become corrupt but what - and how do I resolve things?
