Re: The camera starts scrolling without touching mouse

I have edge scrolling on.

Could you test if the same happens if you have it off ?

I have edge scrolling off and I occasionally have the same problem. It seems to stop after awhile, but the last time while it was happening I couldn't center on any of the sims, or make them do anything. I went into build/buy to see if that would stop it. It didn't, but it stopped a short time later and worked normally.
