When I receive an email with an attachment and click on the paperclip, some
attachments have a picture of a little white square with about 3 red and blue
dots on it instead of a picture of a little envelope. When I click on it to
open the attachment, a window opens that says: "This file does not have a
program associated with it for performing this action. Create an association
in the Folder Options control panel"

I don't have a clue what this means and I can never open those attachments.
Can anybody help?
