Sending blank emails
My colleague has a problem with her email - when she emails someone with an attachment, the main email text disappears, as if she's sent a blank email.
It only seems to happen when she emails certain addresses, and even then not all the time, but we're tried changing the font and selecting plain text format, and it doesn't make any difference.
Messages without attachments are fine, and forwarding or replying with attachments is mixed, but whenever she starts the email and sends it to certain addresses the emails arrive blank, but with the attachment.
She's on OSX 10.9.1 and using Mac Mail 7.1
Any ideas?
