I was able to deal with this problem by openning the page in excel and
doing a Save As...

I have been creating single file web pages of excel charts and I have
been able to view them with previous versions of Internet Explorer, but
since I upgraded to IE7, I can't view them. Does anyone know what the
problem could be?

PS: I am able to view the charts when I edit the page, but not just
openning it regular.
