media clip organizer

[Marv]

While trying to insert a clip art image, I let the clip
organizer automatically arrange all the media clips in my
computer. Now all the images in any category, including
those images NOT in my computer, show up in the
organizer.

I am not happy with the way the organizer did it. HOW CAN
I UNDO THE FILING SYSTEM SET UP BY CLIP ORGANIZER and
ORGANIZE THE CLIPS THE WAY I WANT TO?

If it cannot be done, perhaps clip organizer can be
deleted and then reinstalled? HELP!

Thanks.
