Fullscreen form problem

Hi all,

I’m building a new site with Flash and have a specific problem with the fullscreen mode. The contact form stops working, it is impossible to bring any of the fields into focus and thus enter any information. All is fine when it’s not in fullscreen mode. The work in progress can be seen here - http://www.cabstudios.co.uk/new/ - if you put the site into fullscreen mode, then click the contact button, you should see what I mean.

Any thoughts?
