When I open a lightbox while running Safari on my laptop it does not work. The black background comes up but nothing else. Also, when you click the back button the black remains. Refreshing the page makes it go away. Everything works fine on a iPad and iPhone running Safari. On a related subject, the captions on my lightbox photos don't show up in IE. I usually run Chrome where I've had none of these problems. The browser is Safari 5.1.7 for Windows.
Update: Captions are gone from all lightboxes in all browsers for some reason. Working on this issue. Firefox works great and I think IE works good too now that I see the caption thing is not browser specific.
