I thought maybe the frequent design changes had confused it so I exported my blog, deleted it and then tried to create a new version and import the content. Blogger just refused point-blank to have anything to do with the file. Arrrgh... undelete... undelete. Luckily I managed to restore the old version. You do have to wonder how committed Google are to the Blogger service though.Hmmm... maybe I should try it in Chrome to see if that makes a difference.
Apparently it does because changing the design of this blog in Chrome worked flawlessly. So there is a need for chrome then
