BuddyPress.org

Just posting this for validation before it goes in the bug tracker, but with WPMU 2.9.1.1, the javascript that allows you to create categories — both in-post on /wp-admin/post-new.php and on the categories page at /wp-admin/categories.php — breaks down.

You can still create a category, but you have to refresh the page to have it visible. The javascript that shows the new category, highlights it in yellow, and checks it fails.

This isn’t a deal breaker, but BuddyPress 1.2 beta is the only plugin running when this happens. Deactivating it solves the problem.
