Topic: IE7 and body background image

The combination of a Flash object and a background image defined in the body section of a CSS does not seem to work.
The sitemap page is working as it should; the contact page isn't.
Any idea?

P.S. Thank you for the Simpleviewer 1.7.1 update; besides solving the Microsoft Active Content issue, it also makes my website compatible with the Opera browser. So all browsers are supported now, except this new version of IE.  :(
