I installed metapost into my DNN iinstallation.  I tried it out and it worked fine for Magic Content.  I then added a new portal.  I added some pages to the portal and then tried to edit them with WLW.  I could net get connected no matter what I tried.  Finally, I added the metapost module to a page on my site, went to settings and found that my new portal was not editable..  I clicked edit, made it avaiable for metapost and all was well. 

One thing I found is that I could not see any modules on my site using WLW that had no content so before I could edit any of the content, I had to add some content to each page.

Another thing I found a bother is that a module that is flagged to show on all pages shows up in WLW multiple times.
