I just encountered this problem a few minutes ago. When I click on a message in my "Sent" mail folder, it shows me a completely different message from the one I'm trying to read. I've tried various messages, and the same thing happens. Instead of the one I'm trying to read, a much older message is displayed. (Just FYI, when we installed Mozilla, we transferred everything over from Netscape.)
Is this a known bug in Mozilla, and if so, any suggestions on how to correct it? Thanks! Sue
