I am using ZD v.7, on a Windows 7 pc. All was working well until a couple of weeks ago. Now the sync is malfunctioning. Each time the "send/receive" is activated, all the messages in the inbox are downloaded again, despite the fact that the delete after delivery button is ticked. This generates error reports every few minutes, as per the following:-
