Mootools: Formcheck tips over lightbox

I have a form on a lightbox, that form is server side validated with PHP (no issues there) and client side validated with formCheck for Mootools, Is it possible to show the error messages on top of a lightbox?

By default it shows them under the lightbox, and therefore useless to the user filling the form, since they cannot be seen.

Any way of getting over this?
