I'm a little mystified about the preview pane and its underlying web content.  I know that the client locates the web content using the BaseUrl setting in ClearCanvas.Ris.Client.WebResourceSettings.  However, I'm seeing some strange and inexplicable behavior.

Even when I shut down my web server (via the IIS control panel) and rename the RIS\web folder on disk, my client still loads the preview pages!  Even after rebooting.  Stepping into the code, an example URL is http://localhost/RIS/preview/performing.htm.  I've configured IIS to point the RIS virtual directory to a non-existent folder (renamed the folder after pointing IIS there).  Attempting to load that page in chrome manually verifies that it's not available.  Where is it getting the document from?  I see it go in here: _webBrowser.Navigate(_component.HtmlPageUrl); and it comes out with a valid document, but from where it came, I can't fathom.

I came to this observation while trying to figure out why the client running on my dev box shows the preview pane, while the client running on a test machine (with its BaseUrl pointed at the server's URL) does not.  Obviously, my attempts to isolate the problem have run into a wall.  Help?
