Bill,

here are a few issues mixed.
Sometimes IE / Webbroser returns the HTML
which he already refomated.

I found the IPerstist* interfaces to be less
affected, but I won't guarantee here.

If you absolutly need the "raw" source,
I'ld suggest to use WINAPI directly,
either UrlDownloadtoFile (UrlMon)
or a variant of the example in MSDN
which AFAIR uses Internetreadfile.

HTH
