So I have tried to install version 4.x every time I get a notification that a new version is available.  But every time once I get 4.x installed it will not connect to the server for sending or receiving mail.  Version 3.99 (or whatever the last 3.x version is) always worked fine.  So every time I install a 4.x version I end up having to restore my computer back before the install to get thebat to work.

Any suggestions on why it works in 3.x but not 4.x?  I am getting really tired of doing the restore.
