[imp] disturbing folder issue when deleting folder that contain msgs

[jkpsj]

imp3.2 courier-imap

i have folders setup as follows:
INBOX.f1
INBOX.f2

INBOX contain no messages as i moved them to folder f2
f1 is empty
f2 contain couple messages that were moved from INBOX.
Trash is empty

** and quota usage displayed as 11% 

i selected f2 (folders.php) and chose 'Delete folder(s)'
2 prompts came out and i confirmed both of them.

result: f2 folder was deleted. BUT quota usage *STILL* showed 11%
the problem can be reproduced.

i can only deduce that somehow, the actions above, DOES NOT trigger courier to update maildirsize.
am i correct? or could this issue have been discussed b4 BUT i couldn't locate it in the archive ?

please advise.

rgds.
