Hmmm....
That puts a new spin on it. I don't recognize that specific VB sample, but I tried using the AppWizard to create a simple app with a Web browser. Worked fine. Same with an old VB HTMLViewer program I was playing with a few years back. It might be something specific to the sample code you're using, maybe setting a property to volunteer authentication credentials? If you can point me to a source for that sample, I could try it. Other than that, I'm still stuck.
