I found another bug with the notifications thing. We already know that we get the yappari chat notification in a seperate window than the actual chat window. Now, If I also get a sms from any number and it is still unread and present in the notification window, clicking on the yappari notification opens the unread sms instead of the yappari chat.
Scorpius - I guess this has something to do with the notifications being programmed with messaging functions of maemo.
