go to control panel/Appearance and Themes/change the desktop background/Customize desktop/web tab and see if anything is loaded there.

And you can delete the things you downloaded earlier.

I checked the themes etc Joe,nothing looked out of place in there,i was not sure if when the Smit scan changed my wallpaper when I rebooted after the scan had anything to do with it?
I can change themes and screensavers ok,when i change the desktop theme and save it comes up ok,when i go back into change themes again,the actuall theme which i have on the desktop is highlighted but the the screen in the theme programme just shows black.
If i click on another theme,then click back to it, it then shows me a screen with my current theme?So basically i just click once on another and then straight back i dont change themes.
As I said all works well only the icon appearance.
Thanks Joe

Joe when i refered to, when i was changing themes, i meant desktop background,I cant find edit so sorry about xtra post Thanks

So it is the preview window of the walpapers that comes up black.. Strange , but indeed not a real prob or anything.

I'll have a look anyway to see if there is a fix for it.

Ok thankyou Joe
