Ok, did more tracing and it appears that it's not the mailbox readonly  
status that is causing this.  It appears that  
imp/templates/basic/mailbox/navbar.html.php is what displays the form  
field for the 'Mark Messages' drop down list.  I placed a debug  
statement in this code and it looks like this statement:

<?php if ($this->flaglist_set): ?>

is not true and therefore, the code inside that if block, which  
displays the drop drown is not included as a result.   When I do a

Horde::debug($this->flaglist_set);

I get :

2012-12-19T14:27:29-05:00 DEBUG: Variable information:
array(0) {
}

Not sure what this means but it sure doesn't look like a boolean value.
