Hi Edward, just 1 thing in my mind that can cause this. whenever a form contains only one element it calls submit automatically on the click of enter while focus is in that element, so you may not need to use onkeydown="mykeydown()" but i think this is the behavor of IE only so if you want other browsers so you will need to check the browser inside your function.
