I use fancybox 2 to overlays, and after using fancybox 1 for a long time, there is a weird thing in v2. In v1, if I loaded new html via ajax, with new fancybox link in it, I had to call fancybox again for the new link. In v2, it seems that after new html is loaded, new fancybox works without calling the function again. However, I don't see any prove if it works that way in v2, neither in source code, nor on the web. In the future, I don't want troubles with fancybox, so I had to be sure of it, before continuing work.
Thanks
