I finally figured out how to edit existing posts in my blog using WLW 2011.  It’s actually simple but not obvious with the Microsoft style of menus and toolbars.

First you have to click the primary app menu in WLW that looks like this:  image_thumb

Then click on Open Recent Posts.  Don’t click a choice on the fly-out menu to the right, just click the menu option itself.

Finally, the traditional File/Open dialog appears.  On the left side you will see your specific name.  Click your name and all your previous blog posts are listed. image_thumb[1]

  From there you pick one, edit as needed and just click Publish to save it back to your blog.

So far I like WLW 2011 – does a good job where other web-based editors don’t.
