[Evolution] Unable to attach Inbox email to a message

[Louis van Dyk <louis qdcec co za>]

Hi

I am running evolution-3.38.4-1.fc33.x86_64.

In the past, I could write a message, and open the "Attachment Bar" at
the bottom, and then drag a message from my INBOX into it in order to
attach the email to the message.  I can't seem to be able to do that
anymore.  Nothing goes into the attachment bar when I try.

Any ideas where I can look?

Thanks,
Louis
