Soft key crashes program but works in Flash 8 emulator

Question

I am developing for the Nokia E62 in Flashlite 2.1 using
Flash 8, The E62 is a Symbian S60 v 3 phone with a 320 x 240 pixel
screen. The Flashlite 2.1 standalone player works fine on it but
the phone comes only with a Flashlite 1.1 player. Flash 8 does not
have a Flashlite 2.1 device profile available for the Nokia E62, so
I am using teh generic Windows Mobile profile as it is the only one
with the proper screen size.
My program works on the emulator but when I test it on the
phone, pressing the soft key crashes the program (my program quits
but the standalone Flash 2,1 Player dos not die and I am returned
to its menu fo choosing a movie to run.) In a previous version of
the program, I was able to make the soft keys work fine on the
phone so I know that the phone supports remapping softkeys.
I am working in fullscreen mode so the Symbian system labels
for the softkeys are not visible. Nonetheless, my past experience
is that the program will crash if I do not use the fscommand2
command:
fscommand2("SetSoftKeys", "Menu", "Submit");
Anyway, here is the code to handle softkeys which crashes on
the phone when either soft key is pressed, but works on the
emulator:
fscommand2("SetSoftKeys", "Menu", "Submit");
var softListener = new Object();
softListener.onKeyDown = function() {
var code = Key.getCode();
switch(code) {
case ExtendedKey.SOFT1:
_root.gotoAndStop(3);
break;
case ExtendedKey.SOFT2:
submit();
break;
Key.addListener(softListener);
It appears that the phone crashes in the
softListener.onKeyDown routine and not later on in the submit
function.

What is the difference in how soft keys are used between AS 1
and AS 2?
I was publishing in Actionscript 2, but you are right, my
code is AS1-style on the timeline, not AS2 using external class
files. I wanted to publish as AS 2 to use strict typing in order to
debug more easily.
Except that in the snippet I sent, I declared
var softLIstener = new Object() instead of
var softListener:Object = new Object()
and I did not do the type declarations in the function
definition...
So should I get rid of all the places where I did declare
types and publish as AS1? Or do the declarations consistently and
keep it AS2? If this is Flashlite 2.1, doesn't that mean I get
Flash 7 - style AS 1 and not Flash 5 style? AS 1 prior to Flash MX
is really limited and I don't remember it well. I thought AS 2 was
backward compatible with AS 1 so that my hybrid code should work as
AS 2. It does in the non-mobile versions of Flash...
