Could you please change the CSS rules in
wordpress-seo/css/metabox-tabs.css so that they only apply to the tabs generated by WordPress SEO? CSS rules with scopes like
.ui-menu are broad enough that they apply to any implementation of JQuery UI Tabs on the post editor screen. I'm just about to release version 7.3 of SEO Ultimate which uses metabox tabs, but as it stands, WordPress SEO's CSS rules are wreaking havoc in SEO Ultimate's metabox. If you could please narrow your plugin's CSS rules so that they only apply to the WordPress SEO metabox, I'd be most appreciative. :)

P.S. I would've emailed you, but your website makes it pretty clear you want all plugin correspondence on this forum, so I hope I'm posting this in the right place.
