Ok, so I have created an outside app to send messages to the website remotely. everything works ok, except it duplicates the conversations in the list. attached a screen shoot to show you what i mean. 

the message on site shows only 1 per message thread and shows it as a new message when sending it.

but my messages make multiple entrees per message in a thread ( conversation )..

I have dug all through the database to clone the process as much as i can. but i must be missing something. anyone mess with messages and ran into this problem?
