I am back on NORMAL Ol'Buzzard desktop - I Hope. As you know from all my complaints I could only read the most recent post on my reading list. On the Google forum I found that many bloggers were having the same problem. It turned out that somehow (???) my desktop had been switched to 'draft Blogger'. In the address block at the top of the page the blog was coming up as reading blogger/draft. The fix was to go into Edit User Settings and deselect 'draft Blogger.'
I have no idea how the switch from normal blogger to draft blogger occurred. Magic - I suspect.
