Im using an IMAP account.

When I have an attachment open, and then change emails in outlook to
view another email, Outlook decides to create a second copy of the
email with the open attachment, and "mark for deletion" the first
email. In doing to Outlook locks up as the copy is created and
uploaded to my IMAP server.

Does anyone know how to stop it doing this? Im using Outlook 2003.
Many thanks!!
