Scroll perfect on iPad, different on PC

Is there a way of making the content scroll the whole page rather than just the iframe content?
On iPad the same page scrolls as if no iFrame is used. Can the same be achieved on a PC?
I have used the following shortcode
[iframe scrolling=”yes” src=”http://www4.amstock.co.uk/Eastbourne/salestock.aspx?frame=1″%5D
Here is a link to my example
