Odd bit of text added when replying or editing a reply.

            x              (x)                    I've had this happen here recently. I'll reply to a post and at the beginning of the reply the line will start with this;
              X                  (X)                      Start of reply text here......

I see it also does this on a new topic started be me.
I caught it this time around and edited my reply to a post removing the  strange addition and then had it show up at the end of the my reply. Has anyone else noted this?

I have only seen it in your posts. What web browser are you using? Du you have any addons that may be causing this?
