I have noticed that e-mails with large attachements take a while to
download, and Evolution does not give much detail.  While Evolution is
retreieving the next message it displays the old message and the only
indication that it is doing anything is a message that says, "Retrieving
message <some-long-string>..."  A less perceptive and less patient user may
think that Evolution has crashed or is 'frozen'.  Can we display a small
dialog that indicates the download progress for the message/attachment?

FYI, I'm connecting to the Exchange server with Connector.
