While I am no longer working on Windows Live Writer I still talk with that team and today we announced that there is an update to the Windows Live Essentials suite — http://windowsteamblog.com/windows/b/windowsexperience/archive/2012/03/20/update-for-windows-live-essentials-2011-now-available.aspx.
When talking with the Writer team they said they just made QFE level bug fixes and did not add new features to the product. As always I would recommend updating as things should be more stable than what you have today. You can get the new version from http://get.live.com
As an aside working on the Photo Gallery team we did make some improvements when working with web services in that users of flickr, Facebook, or Geo-tagging will enjoy and that should be reason enough to update your build.
