I love the kubrick theme. I'm using a modified version on one of my sites. But I'm still unable to clean up all the html errors. There's a few DIVs that are illegally placed within a TABLE element (when they need to be inside a TD).
There's also a series of problems in the css: ://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fthemes.tikiwiki.org%2Fstyles%2Fkubrick.css&usermedium=all
