Possible Bug: Validator seeing different source code than browsers

When I enter the site I am working on into the 'validate by url' option
in the validator, it returns a series of xhtml errors. If I copy paste
the source from the page into the 'validate by direct input' option, the
page validates fine. When I revalidate the url with the show source
option on, the validator is seeing difference source code than if I view
source from either IE or firefox.



We are using .Net 2.0, and some of the code that seems to change from
the browser to the validator is



 <form method="post" action="Default.aspx" id="aspnetForm">

<div>

<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTEwMDUyNjYzMjhkZAmDsHsZo3g5/8ZaMhn69mJYphmK" />

</div>



(Which is XHTML valid), to



#  <form name="aspnetForm" method="post" action="Default.aspx"
id="aspnetForm">

# <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTEwMDUyNjYzMjhkZAmDsHsZo3g5/8ZaMhn69mJYphmK" />



Which is not. I'm not sure how the validator can see different code than
the browsers...



The site is: http://stage.closettailors.com/
