This is more of an academic interest at this point, but is there a way to use the TempDirectory property vice putting it in the web.config file?  I cannot seem to get that property to work.  The program creates a resource file called "processing..." for each file, but then the app craps out with saying it cannot find the generic temp folder or throwing some other error depending on what settings I have, most notably setting the property for using the system temp folder by default.  However, once i set this in the web.config file, it works like a charm.
