Page position

I have a two form application, form 1 is a list with each item having a link, when I click the link it opens the second form to show a detail view.  This all works fine except if I scroll down the list on form 1 and open the detail view, on hiding the detail form to return to the list it refreshes the page and returns the list back to the top rather than leaving the list in the same position as i originally left it.
 
Does anyone know way around this.  Thank you

Richard
