TXGuy I love you. Like magic your simple trick worked. Thank you from a grateful older lady, who is not computer savvy.

Oh, thank you so much!! Problem gone.

I have lost all of my bookmarks. I go to the bookmarks menu, choose Organize, and I see the 5 backup files. However if I try to restore to one of them, I get the message "Unable to process the backup file". I sure hope there is something that can be done about this.
