Thank you for you reply, jaem.

- Yes, Iam talking about the Conversations app, default app in N900. Even after install "Conversations desktop widget", the number of new message displayed at bottom left of the table in Desktop is 1 (but it shows "No new message")

- I mean that message status is still unread. Not one more message. As you said: message is not getting marked as "read". And if I have more than 1 message, all messages not getting marked as read too...

Iam sorry about screenshot.... Iam trying because I've just use N900 for some days. Will be updated soon.
