jquery slidedown issue on iPhone/ipad with scalable background
I have an issue where a drop down menu using query slide down performs erratically on the iPhone/iPad but works fine in the browser.  Error in question can be seen here;

http://cl.ly/173d1y0Y1s1l2d0E0c3n

the site in reference can be seen here;

https://s3.amazonaws.com/nav-reference/nav-reference/nav-reference.html

the css;

s3.amazonaws.com/nav-reference/nav-reference/css/nav.css

I have a feeling it has something to do with the full-sized scaling background  and the img.bg rule in my css but I'm not really sure why it's causing the error, and why its in only the mobile safari.  Any help would be greatly appreciated.

thanks!
