Zenworks for Handhelds 6. 5 & Pal Pilots

Two questions.

1 - Is there a patch/upgrade to support the Treo 650 Palm OS v5.4.5? The
app loads onto the Palm, but does not appear to work (No password
challange, etc.)

2 - I've got it installed and somewhat working in the Treo 600 Palm OS
v5.2.1. At power on it requires a password, but failed atempts does not
destroy any data, or force hard reset.

Thanks in advance.
