title: Thickbox or something similar with a 100% window height
body: <p>I am building a site with a video background and in order to keep that video playing with the visitors are browsing the site have gone with pop ups. I have used Thickbox to do this however it appears that thickbox will only allow me to use defined height where as I would like it to have a height of 100%, does anyone know if this is not the case or how I would achieve something similar with another js script?</p>
  
  <p>Have tried using fancybox however which worked perfectly however it seemed to not like working with another js script, ie. the video background? </p>
  
  <p>Please someone help as this is driving me mad...</p>
  
  <p>This is the website, apologies in advance for the title it is just a holding page i use sometimes.</p>
  
  <p>Thanks in advance.</p>
