Users not displaying in box

I'm not sure if we have the same problem,
My problem was that if the list-of-users option was chosen (and not the autocomplete option),
the list was empty.
I found a bug in the "_messagebox_get_users" function (line 110).
the query isn't correct, the status of the users is vital to distinguish between offline and online users, and this field is missed in the "select" part, but not in the parameters part, so caused a mistake..

My function look like that:
/**
* helper function
*/
function _messagebox_get_users() {
global $user;
$items = array();
$time_period = variable_get('user_block_seconds_online', 600);
if(!user_access('send global messages') &&
$user->og_groups && count($user->og_groups) > 0) {
$users = db_query("SELECT
u.uid,
u.name,
IF(u.access >= %d, 1, 2) as status /*Miriam add*/
FROM {og_uid} ou INNER JOIN {users} u ON ou.uid = u.uid
WHERE
ou.nid in (%s)
AND u.status > 0
AND ou.is_active > 0
AND u.uid != %d
AND u.uid != 0
AND u.login != 0
AND u.status = 1
ORDER BY
u.status, u.name",
time() - $time_period,
implode(',',array_keys($user->og_groups)),
$user->uid);

}
else {
$users = db_query('
SELECT
uid,
name,
IF(access >= %d, 1, 2) as status
FROM
{users}
WHERE
uid != 0
AND uid != %d
AND status = 1
ORDER BY
status, name', time() - $time_period, $user->uid);
}

while($uid = db_fetch_object($users)) {
if($uid->status == 1) {
$items[t('on-line users')][$uid->uid] = _messagebox_shorter_name($uid->name);
}
else {
$items[t('off-line users')][$uid->uid] = _messagebox_shorter_name($uid->name);
}
}

return $items;
}

Hope it will help others!!
