Hey folks! Every now and then (it's becoming more common, actually) Mail will note that a new message has come in, but when I click on the new message, I find that it has replaced the new message with an old message from my Inbox (or a folder). In order to read the actual new message, I have to go online to my email provider to read it. Really. Annoying. Does anyone have any suggestions as to how to fix this? Thanks in advance!
