[Nobody]

I've just had a weird thing happen to me. When I logged in to my computer I discovered that the mail icon in the dock had disappeared. No big deal, so, I went and put the icon back.
When I went to check my mail it showed that it was receiving messages but it never displayed them. I checked all my mailboxes and they were nowhere to be found. I checked my mail account from my isp's web site and they were not there either.
I checked my mail settings and they haven't changed any.
This is the first time this has happened. I've only been using Jag/mail for about a week, now. Anybody else have this situation?
