I find it very frustrating that when I fail to connect to a server for various reasons that the Navigator switches to one of my connected servers.
Example if I try to log in to new server and it fails, the navigator instead of just staying on my failed server, scrolls to a server that is is already connected to. Then I need to navigate back to the entry I am working on and start all over.
I would like the Navigation to just remain where it is when disconnecting form a service.
Could you try to Uncheck "Auto select item on tab focus" in File->Options?
