How to fix: Clicking ‘Quick Edit’ link in Admin (edit.php) makes posts disappear?

Well.. that had me stumped for a while!

I had replaced WP’s jquery v1.6.1 with a Google-CDN jquery v1.4.2 in my functions.php.

    wp_deregister_script('jquery');
    wp_enqueue_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"), false, '');

Learnt a few things along the way.. thanks, Tim
