Problems with text messages

I've got a Bold 9780 and just today there's been something odd with how my text messages are showing. I texted someone and it was normal and showing my messages and the received messages.
I then sent another text and when they replied to it, the new message showed above my sent message. instead of after.
then i replied to the message and when i'm viewing the whole convo i can't see my latest sent message. I can only see it when i'm lookin at my inbox.
I'm sorry if this is in the wrong place but i've tried searching online but no one has an answer about this.
anyone have any suggestions ???
thanks

Probably just a bug with OS 6, My 9700 would do this as well, Only happened sometimes but it was a **** off when it happened.
