Since I upgraded to the latest version of wp-e-commerce (3.6.10 rc2 & 3) - While adsense manager is activated it messes up the settings area of e-commerce.
If I comment out wp_enqueue_script('postbox'); in line 27 of class-admin.php in adsense manager v3.2.13 then the settings area of WP Shopping Cart works as expected.
Is there a better way to fix this problem as I guess the postbox script is in the adsense manager script for a reason?
