I am having the same issue as you can see here.
I checked all the paths and tried the javascript and css linking compressed and not, everything looks right.
I am not sure how to proceed or what might fix this? As mentioned in the previous post, it just works perfectly in Chrome and Firefox.
Just in case someone (in IE) is not see what I am seeing, the Fancybox is working just fine - it pops up the correct slide and dims the rest of the viewport. Forward and back work and you can still press 'Esc' to close the Fancybox. What is NOT working is the Close (X) in the upper right does not appear - and the forward/next and back/previous images do not appear as expected on hovering the right or left of the slide (popup).
Any help (and especially a quick-easy fix ;) will be greatly appreciated! Thanks - Jeremy
FYI - jQuery (hosted from Google, latest) is 1.4.2 and Fancybox is 1.3.1
