I am experiencing a problem with Apple Mail. It times out every 30 minutes or so with a message stating unable to connect to server, I just click the message and it starts receiving ok. Sometimes when I send it hangs and will not send until I quit and reopen the program. I ran the Mail connection doctor and it checked out ok. Would an upgrade to 10.6 take care of this? I'm not sure about this as everything else works ok and I hate to upgrade because other problems might crop up.
