Can not insert images after SSL swtich on in admin

Hi I have just turned on SSL in my admin using these settings in my wp-config
define('FORCE_SSL_ADMIN', true);
define('FORCE_SSL_LOGIN', true);

Once on it seems that the 'force_ssl_admin' is stopping me from inserting featured images or using the media button for inserting into posts. Any thoughts on how to fix this?

Cheers
Shannon
