Here is the exact same process (no code changes at all). All I did was put a break in the form keypress event so that it would stop there when I pressed pagedn. In testing this, when the break occurs the value has changed after typing "123456" and pressing pagedn (as you can see below - in fact the valid processes). However, without the break in the keypress event, it does not.
