Subj : MsgBase.put_msg_header() failing to save header

I have a message reader script for Synchronet that I've written in JavaScript. 
I've written it so that when the user reads a message that was written to them,
it will mark the message as read (by setting the MSG_READ attribute).  I'm
using the put_msg_header() function to save a header with that attribute, and
it seems there are some cases where put_msg_header() fails to save the header.
I am checking to ensure the message was written to the user, so I don't think
that would be the issue..  I did notice that one area where saving the header
is failing is a FidoNet area - I'm not sure if that matters though.

This is how I enable the read attribute (msgHeader is the message header
object):

msgHeader.attr |= MSG_READ;

I've tried calling put_msg_header a few different ways, using the message
number vs. message offset:

msgbase.put_msg_header(true, msgHeader.offset, msgHeader);
msgbase.put_msg_header(false, msgHeader.number, msgHeader);
msgbase.put_msg_header(msgHeader.number, msgHeader);

I tried the 3rd one since the first parameter is optional (according to the
Synchronet JS docs); I've also seen examples that omit the first parameter and
just use the message number.  Where it fails, I will exit my message reader and
then read message again, and it thinks the message has not been read.  I've
also seen put_msg_header() return false in that case.

Why might put_msg_header() fail?
