Thanks, but still no luck. One thing that seems out of place is that the registry key
"HKEY_CURRENT_USER\Software\Microsoft\Windows\Curr entVersion\Explorer\Shell Folders"
contains a value "C:\Documents and Settings\<username>\Recent"
However, I do not see the "Recent" folder in explorer. When I tried to create a new folder and name it "Recent" it said the folder already exists, but again I can't see it and hidden folders are visible.
