Image pop up with Highslide

Hi all,

First of all thanks for your wonderfull component.

I'm about to release the iphone version from my site but I'm meeting a bug.

On the page iphone.2xaventures.net/fr/gave-doloron/parcours-a-tarifs.html
When I try to open a pop up image in a content to zoom in, the pic disapper and there's not pic zoomed in on screen.

Have you got any soluce ?

I have the exact same problem at www.chaniaweb.com (when you go there on an iphone that is)

With Highslide and using the lightbox effect of Phocagallery. In both cases the image dissapears as soon as you 'touch' the thumbnail. I've tried all different iphone and global settings, but nothing worked.
