IE8 Navigate in "Protected Mode"

If you spawn an IE session in your development read on…

I have an application that is posting data to a webpage from a client app using the IE.Navigate API.  The problem was that in IE8, the server never received the request.  Instead (when Visible was set to True), the window just opened and then disappeared.  I finally discovered the reason.

In the “Internet” zone, the “Enable Protected Mode” setting was checked.  An admirable security feature, it can be awfully annoying to the uninformed (as security features typically go).  Now, note that my URL is on our Local Intranet.  Regardless, by unchecking this option, the application immediately began functioning properly again.

Good luck with your IE8 testing.
