I would like you to browser-test a page with a test version of this menu here
I tried windows versions of IE6, opera6, netscape 6, mozilla0.9.9.
Please let me know whether you see the blue words in the DHTML DynamicMenu, the arrow to the right of the words 'symposium 2002' and whether it expands when you hover over 'symposium 2002'. Oh and when hovering the color should change.
Don't try to click the links, they are dislocated.
Please mail me a report with your operating system and browser name and version.
