I was in the process of redefining an existing custom module I wrote when I received a blank white screen, indicating that something is hung in DNN on my local machine. Facts:

• SQL Trace indicates almost no Database activity. The only thing showing is "exec dbo.DeleteUsersOnline @TimeWindow = 20", every 20 seconds. 
• FileMon is showing only a quick open and close of Default.aspx.  After a delay there is an unsuccessful attempt to open just about every file in the site.
• I CAN browse an HTML document in my root http://localhost/DotNetNuke
• I have granted full Control to the account ASPNET on the DotNetNuke folder and all subfolders
• I have stopped/restarted IIS.
• I have cleaned out "Temporary ASP.NET Files" folder and "VS WebCache" folder.
• I CANNOT open the project in Visual Studio because VS cannot connect to the website.

Does anyone know what the problem could be?
