This may be true, since I'm using a hosting service, which I have no control
over how they configure their IIS Server.

It doesn't like PUBLIC?  I went to google.com/m to see how they use it, and
they are using public.  I copied their line and pasted it in place of mine
and I think it breaks MobileOK.  The results ani-image is moving, but it
never goes to the next page.  I removed the DOCTYPE and it works, added it
back and it freezes again.   Google uses:
Now, this completely messes my site up, so I removed it again.
I thought I understood the meaning of doctype, but I must be missing
something, even still.

Ok, after that being said along with the information mentioned above, I'm
noticing that MobileOK is looking at more of what the server says, rather
than the code within the page says.  I'm not so sure this is a good idea or
why we have HTML tags that are ignored, since most people like myself use a
hosting provider and have no control over how the server is configured.
That being said, I added a Header of ContentType within my server side code
and it cleared up some of the errors.   I did this for all my pages as well
as the style sheet.

Note: MobileOK, has the message of:
The document is not served as "application/xhtml+xml"

No where do I specify it is, so why would it be looking for ASP pages to be
served as an application?   If I set my pages to this, it prompts to
download the page instead of displaying them.

I got another error, before MobileOK stopped working all together for me.
