I am looking at the elements in the document after downloading it using
MSHTML.Document.  I've tried System.Windows.Forms.WebBrowser along with the
ActiveX WebBrowser (I think it was something to do with accessing the MSHTML
document that stopped me from using the former when I wrote the program) but
I'll give System.Net.WebClient a try- perhaps using it to load the "main"
page (see my other response) will fix the problem.

The "main" web page is a list of service requests links.  My program is
loading the main web page and then loading each individual service request
link.  At various points (seems to be random), when attempting to load a
service request page, a runtime error is returned.  I've tried slowing the
program down and am convinced the time between downloading each page is not
the cause of the problem.

When the runtime error is returned, I try downloading the same service
request page again after waiting 30 seconds.  The runtime error will
continue to be returned.

If I open an instance of IE and load the "main" web page, the runtime error
is not returned and the program continues.  IE can be used to load the
"main" web page on the computer running the program or on a different
computer, same results.

What confuses me is why I can not use the web browser control (again, I've
even tried a separate web browser control) to load the web page and get the
same result.  It seems to me that when the page is loaded with IE, something
additional is happening that does not occur when I am loading with the web
browser controls.

Ideas on what that "something additional" could be are what I'm hoping to
find (or a solution, of course).

I hope that clarifies things.
