I'm working on eshop website and want to make the product page apear in a showbox. But it' difficult to make a purchase when I'm using mobile devices. First of all - it's imposible to type anything in any text area of a showbox page. All the window starts to jump and tryes to close the keybord then appears again.

To check it please go to my website http://soladance.com/ and push the violet button in a right top corner using any mobile device.

I've already tested with no any of custom code on absolutly clean website and it acts the same. As I wrote before - it works only on Windows Phones.

The second problem is that it's uncomfortable to use popup windows on mobile devices at all, so it would be nice to make it posible to be shown as a showbox on pc full version and as a new window on mobile version.

Is there any kind of solution or some code which can help me to do this for this time before the delevelopers team solves this problem?
