As a guess, I'm thinking something has changed Desktop.ini in your Documents folder.
It's a hidden file so you'll need to enable viewing hidden files and folders to see it.
On my Vista installation, the file contains the following:
quote:
[.ShellClassInfo]
LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21770
IconResource=%SystemRoot%\system32\imageres.dll,-112
IconFile=%SystemRoot%\system32\shell32.dll
IconIndex=-235
A bit more on Desktop.ini
Hope this helps...
