This may not truly be a bug depending on your use-case, but I was not sure where else to file this and in my opinion a lightbox should have the highest z-index.
I just upgraded a site from 5.4 to 6.0 and noticed that the site navigation actually sits on top of my larger images when viewing them from a click with the lightbox mode. After inspecting with Chrome a bit I noticed that RadMenu gets a z-index of 7000 set to it while the fancybox.css file that came with Sitefinity 6.0 only ever sets z-index to around 1000-1004. All I did was increase the values in fancybox.css to 8000-8004...etc and now it works fine.
