Mail keeps adding spurious PNG attachments
When I reply to an email, Mail keeps adding spurious PNG files to my messages. They definitely aren't there when I hit "send" or when they're in my outbox, but they are attached to the mail before the recipient gets it. Sometimes I see them in my "Sent" file, but not always; usually the recipient cannot open them and often I cannot do so either, but when I can open them they seem to show a graphic related to the business of the original sender of the mail that I am replying to (it doesn't happen if I start a new mail instead of replying to one)
Can anybody explain to me what is going on?
