no mail showing - but it's there!
I've been helping a friend (who is running 10.6.8) with an email issue. We thought we'd sorted it (typo in user name) but although the Inbox now says 70 unread emails, the Inbox window is blank. However, if I send him an email it shows in the Inbox (which now says 71 unread but only mine is visible) until we open it to read whereupon it disappears. If we search for my name, the search result shows all email from me and tells us it's in the Inbox!
