This seems a kind of intentional bug to me however I find it annoying so I must report it.
In previously sent messages window, there are three filters as you know. However, the "Sent to this contact" filter depends on the first 6 characters of the email address of the contact whose chat window is open. So the messages sent to two different contacts whose email addresses' first 6 characters match are shown under this filter option for both contacts' chat windows. For example, in our country there are lots of people whose names are
mehmet (note that there are six characters) so their email addresses mostly begin with
mehmet and it causes this problem. Yeah, that is the name of my two contacts who helped me to discover this bug
Either let that filter match the whole email address, if too much load to computer, then at least increase the required character number which has to match with the current chat window's owner, to maybe 10 or 15
And I feel I have to remind this bug
:
Event notification in the info area will not show when "Ctct's activity is not logged"
