--- Comment #1 from Esme Povirk madewokherd@gmail.com --- The first failure is because Microsoft.VisualBasic.Interaction:GetSetting doesn't work correctly when the registry keys are missing.
After working around that, it tries to navigate a WebBrowser control to about:blank and then modify WebBrowser.Document, but the Document object is null.
