Finally back in business. I haven't been able to post for the last few days -- as the posting box was on a loop and wouldn't let me type. You see I updated the new editor as per instructions -

How to enable the new editor

To enable the new editor, first navigate to your blog's Settings | Basic tab. Near the bottom of the page you will see a field called Select Post Editor, and from there you simply need to select Updated Editor and save your settings. That's it!"

Sorry Not Quite - I went back to Setting, Basic and changed back to old editor and wallah (!) the posting box stopped looping and I'm back. Yahoo.
