Local copy of XSLT style sheet doesn't work

I followed the recommendations for "putting mathematics on the web using
MathML", but I can't get the XSLT style sheets to work with Internet
Explorer version 6.0 service pack1. I copied all four of the style sheets to
my web server and put a small test page with embedded MathML in the same
folder as the style sheets. The xml stylesheet instruction refers to
mathml.xsl in the correct folder, but when I try to view my test page,
Internet Explorer appears to download mathml.xsl and try to execute it
locally. I get an error message that indicates the file could not be found
in my temporary internet files folder. Any idea what's wrong?

Here's a link to the file I'm talking about:

http://www.scriptedmotion.com/mathMLStyles/crossBrowserExample.xhtml

The xslt style sheets are in the same folder as the
"crossBrowserExample.xhtml" file. The page displays properly in Netscape
7.1, just not in Internet Explorer.

Here's the error message I get:

  The XML page cannot be displayed
  Cannot view XML input using XSL style sheet. Please correct the error and
then click the Refresh button, or try again later.
