Sorry to reply to my own post, but I neglected to mention that the 
multiple instances of folders disappear when the folder navigator 
"reload" icon is clicked; so it appears to be cache-related in some way, 
especially since expanding-and-collapsing a nested folder hierarchy 
several times in succession (without reloading) results in a *large* 
number of folder duplicates.
