I have a rather annoying behaviour to report.
When you create an email and you attach and attachment then doubleclick on it, the preview does not work, i.e. it comes up blank.
Once the email is sent, this works correctly.
This is a problem because often I am preparing emails to send and I want to doublecheck that all attachments enclosed to the email (e.g. documents or pdf or jpg) are ready to be sent and I have enclosed the correct ones, but I can’t.
