Murray, this happens to me a lot with aol and aim, plus a local net. The fix I use is to log off mail, log onto the web mail site(s) using my browser, log off, and then shutdown the mac for about a minute. (Restart is not as reliable as a shutdown) Then, all is forgiven...

I don't know why this is happening. I've downloaded lots of email without this happening.
