Photography template bug on iPad/iPhone

Hi,

this page,
PHOTOGRAPHY DEMO

the part just beneath the slider, where the B/W pictures are, when you click on a picture it shows a lightbox type full screen box with an 'X' to close.
All fine on desktop computers.
On iPad , 8 out of 10 times it doesn't work... It only opens the photo itself in a new page, not the lightbox.

Hi, any news on this? If there is a template marked 'NEW' and it doesn't work on iPAd, please let us know, so we don't propose this to a client..!
