Robohelp 8 and IPad Safari- Webhelp Issues

Hi,

I am facing a couple of problems with a Robohelp 8 generated webhelp when I open it in IPad Safari. Firstly, once I have opened a pop-up window, I am not being able to close the window.

Secondly, there is a lot of empty, blank space, after the information in the pop-up window. How can these issues be resolved.

Any help is much appreciated.

Thanks.
