[imp] Pref for mailbox_start with "First/Last Unseen Message" not working anymore

[Jens A. Tkotz]

Hello,

i use horde/imp latest cvs HEAD.

Since some days the preference for mailbox_start
(When opening a new mailbox, which page do you want to start on?)

is not fully working anymore.
First/Last page still works fine, but "Page with the First/Last Unseen 
Message" doesnt work.
I always get to first page at all.


Regards,

jens
