At the moment when people book in using the booking form in NC they have the option to click on "Use my details for this booking" when they click on the direct link in an email to themselves. However if they choose to do this when they are halfway through the form it then pings them to the top of the page and they have to scroll back down to where they were. This has to be possible to fix as it is a given on most sites that you will stay in the same place on the page and not get sent up to the top.
