Calendar picker inside a lightbox problem

Hi, I have a standard form inside a lightbox. So when the popup comes up, i see the form in the popup and on the form, I have a date field with the calendar to choose the date. The problem I have, is that the calendar little popup stay inside the lightbox so I do not see the full calendar. Is it possible to have the calendar OVER the lightbox?
