[horde] a strange problem about imp ?

[Mehmet Fatih Akbulut]

hello,
under Imp > User Capabilities and Constraint : there is something >

> Should we allow users to use folders at all? NOTE: setting this to false
will mean there is no place to save sent-mail or postponed messages, along
with the obvious affects of restricting the user to their INBOX. [YES or NO]

assumption #1: if i set this feature to YES, four new options show up. if i
SAVE configuration when the feature above is YES. then i lose all buttons
[compose, search, logout ...etc] in IMP, but there only remains FOLDER ICON
and DROP-DOWN menu which shows the folders.

assumption #2: if i set this feature to NO, sub options vanishes. if i SAVE
configuration when the feature is NO, then all buttons in IMP comes back,
but this time FOLDER ICON and DROP-DOWN menu vanishes.

i am confused ? i want all of the icons to be up the imp . and i want to be
able to navigate among folders when cliking on the FOLDER ICON or when
selecting one from DROP-DOWN menu.

where am i doing wrong ?
help please ...
