Unable to edit Outbox VMails when in Linux Compatible mode

I am using VarAC on Linux using Wine: When Linux Compability is enabled and I attempt to edit a VMail in my Outbox, when I click on the EDIT button, it opens a blank and new message. It does not permit you to edit the original message. When still using VarAC on Line and I disable Linux compatibility mode and attempt to edit the same, then I can edit the message as per normal. For some reason Linux compatibility disables editing a message in the Outbox. Many thanks for a brilliant product !
