A few days ago the text in most of the emails in my inbox disappeared. A few of the most recent ones are fine, and the new ones coming in are fine, but all the others have this problem: the email listings in my inbox are all correct in terms of "from", "subject" and "date", but when I click on one of these problem messages the content has disappeared. Also, very strange, when I click on these messages, the "from", "subject" and "date" headings change to the same headings that are in the most recent non-problematic email that I viewed. Help anyone?
