SweetCaptcha broken since WP3.5

Since updating to WP3.5, the Sweet Captcha I’m using on my BuddyPress registration page fails. When attempting to drag a icon it generates the following error:

Uncaught TypeError: Object function (e,t){return new v.fn.init(e,t,n)} has no method ‘curCSS’

I’m using the included SweetCaptcha javascript files, and jQuery version 1.8.3

I’ve had to remove it for the time being in order to allow users to register, but I would like to re-enable Sweet Captcha as soon as possible!
