I delved into this a little more deeply, and am pretty certain that this problem
is caused by use of the IMP summary block on the portal page.  The
Horde_Block_Imp_summary class creates an IMP_Tree instance, with the
'subscribed' attribute set to true, in the _content() method
(imp/lib/Block/summary.php line 49), as follows:

  $imptree = &IMP_Tree::singleton(true, true);

Since the IMP_Tree object is cached and reused (e.g., when entering the folder
navigator) I believe this may be the culprit--especially since removing the IMP
summary block from my portal layout returned the folder behavior to normal.

Thanks,
