The main catalog is in a hidden file similar to this:
C:\Documents and Settings\>user name<\Application Data\Microsoft\Clip Organizer
The catalog is MStore10.mgc
I can't say why you have more than one Organizer. The Clip Organizer you see in
"My Documents" is the default folder for downloaded clips.
When you right-click the Clip Organizer in the Office tools, where does the path
go?
