I think Drip 0.5 prevents some script from executing correctly. I've encountered the problem when testing DojoToolkit. the easiest way for you to see the problem is to open "http://www.dojotoolkit.org/" and click on "See it in action". In IE there's a list of buttons that allow you to select a demo. In Drip there're no buttons. I've encountered similar problem with parts of dojo not working or not showing.
to be honest i don't know if this is script, or css, or something else. I know that the problem appeared after 0.3. Drip 0.3 worked fine, 0.4 got worse, 0.5 became better.
