Hi,
each time when fancybox's content is swapped #fancybox-wrap (or
perhaps #fancybox-outer) extends to the bottom of the window.
You can see the problematic behavior here:

(click one of the images right hand side)
That's code I've copied from a working page, pasted there.
I've tried removing the highest image from the rel group, different
jQuery versions, placing the jQuery call deeper on the page, using a
different doctype (rather clueless), all to no avail.
Thanks in advance!
