Browser Issues When Viewing Pages in Contribute
When a web page is browsed from within Macromedia Contribute, some content does not appear as expected, or some features do not work properly. This is because Contribute is dependant for some of its functionality on Internet Explorer. Certain content (such as CSS styles) have better support in later versions of Internet Explorer, so users with a pre-5.0 version of Internet Explorer may experience poor CSS support.
The solution: Update your browser.
