John, other users: it appears that Leopard (OS X 10.5) breaks eMA.
When you try to archive any folder, the process stops on the first
message (and all subsequent messages) with this error:

Error -1700 in message: (message name) ArchiveMessage, msg not
archived: SetNewMessageRecord, Can't make "F" into type number.

I know that Leopard changed indexing and updated mail, so the problem
is probably a new format to the messages in the mail folders.
