I've noticed in the latest release when you click the form field 'edit' link and make changes to the field data and then click 'close', you immediately get re-directed to the top of the form like your'e clicking an anchor tag to go the top of the page. Its a bit annoying when you are editing a long form.
FYI it does not do this if you only click 'edit' then 'close' without making any field changes. As soon as your cursor enters a the field edit text boxes and then click 'close' the back to top action is invoked.
