This seems to happen most frequently when I'm dancing and privately messaging at the same time. With my cursor on the message bar if I try to move my mouse to change viewing angles, talk privately to another person, etc. I will frequently have my av move backwards a long distance. Generally, fall of the dance floor. Seems like it has to hit something solid like a wall for it stop going backwards. I've even told the person I was talking to when I come back that I was sorry for that but they often don't know what I was talking about (could be they're just being polite). Other times they do notice it, typically we just a good laugh about it. I've talked to other newbies and several seem to have the same problem. So how do I stop moonwalking? Thanks for the advice.

Thanks for the advice it helped a lot.
