[imp] Problem with sent-mail

[Paul Hancock]

I am running the very latest imp code from cvs.

Sent mail is not being saved to sent-mail.  The setting in prefs.php is:

// save a copy of sent messages?
// a value of 0 = no, 1 = yes
$_prefs['save_sent_mail'] = array(
    'value' => 1,
    'locked' => true,
    'shared' => true,
    'type' => 'implicit'
);

The option to turn this ability off has never been granted to the users.  
Nonetheless, I checked the database, and did not find the value being 
overridden.

Where should I look next?  Is anyone else experiencing this problem?
