From a quick look at the link it appears to be caused by this line of css:
.fancybox-overlay {
position: absolute;
top: 0;
left: 0;
overflow: hidden;
display: none;
z-index: 999999999999;
background: url("http://design.mobulous.com/Watch/css/../images/fancybox_overlay.png");
}
try changing the z-index to something lower, like:
.fancybox-overlay {
position: absolute;
top: 0;
left: 0;
overflow: hidden;
display: none;
z-index: 99999;
background: url("http://design.mobulous.com/Watch/css/../images/fancybox_overlay.png");
}
Additionally you will need to change the z-index on your pollSlider element to something lower too, like 999, if you wish to keep the fancybox overlay on top of your other content. i.e.
.pollSlider {
position: fixed;
height: 100%;
width: 310px;
right: 0px;
margin-right: -310px;
z-index: 999;
background: #e6e6e5;
}
