Disabling notifications during a presentation is a must to do for 
everybody. I had my share of "fun" because of that. :)

But back to the IMAP problem, as far as I know the issue is that the TCP 
sockets used have a very large timeout. So a socket is opened towards 
the server, you suspend/resume. From the app point of view, the socket 
is still open, but the server closed the connection meantime. The app 
(the IMAP agent) just sits and waits for the data without being notified 
that the socket is not valid anymore. The timeout is 20 minutes or so...
We need to workaround the system's timeout for tcp socket and detect the 
network loss in another way.

I know this doesn't help the user, I just try to give an explanation 
about the technical reason for the problem.
