Slider Links not working


I'm using a plugin called Slider Pro inside UpFront. Everything works fine, but if I link an image to an URL, the link appears on the status bar (i.e. the browser recognises it as a link), however the link is not clickable for some reasons. I've been trying different settings with no luck.

Can anyone inspect my HTML/CSS and advise if there are any abnormalities?
(Please refer to the grey bar with title "Our Corporate Founders" for examples of the problem).
