I mean that the threads will just disappear even though I don't exit or end the conversation. I noticed a possible link - last time I was typing a message and got an email it kicked me out of messenger completely and the chat thread was gone!?!?!
When BB messenger starts getting weird on me I do a battery pull and that tends to fix it for 3 or 4 weeks until it's time to do it again... top quality firmware QA on these things.

This happens to me in AIM a lot, do a battery pull and it should work. What I also did is cleaned up my web history, and cache along with the call logs SMS etc. Hope it works for you
