Strange issue, outgoing messages are sometimes repeating

This has started happening over the last couple days, I'll be having a BBM conversation with someone, and I'll send a BBM, and it goes through and is delivered/read...later whether they've responded or not, I'll open BBM back up and go into that chat, and the previous message that I sent (and was already confirmed to be sent/received/read) is also appearing in the text box as if I'd just typed it out again, waiting to be sent...I have to clear it out to type in a new message. Has anyone else seen this behavior?

have not seen this issue at all. Which OS are you using and which BBM version?
