That's an interesting post. I'm not sure the freezing problem has been completely fixed though. Admittedly, in my own testing, using two avatars on two different viewers, I was not able to produce the freezing effect. But still, at the times when I experience the freezing, it often turns out there is someone else trying to sit on my vehicle also. That's why I think the two are related. I don't grant controls to anyone but the owner so it can't (shouldn't) be a problem of confusion of who has the controls. I'll try the suggestion of wearing an invisible object that encompasses the entire vehicle and test that. Thanks again.
