Maybe it could be the way my keyboard/mouse is set up but every time I try and scroll it doesn't move softly. It tends to go flying left or right. I can never get the camera centered like in the sims 2.
Do you have this issue too? If not, I guess I'll change my mouse/keyboard settings.

I had this at first. After a while, I got used to the controls. It hardly happens to me at all any more.

Ahhh, ok. I didn't know if it was me or the game. I'm pretty sure I can get used to it though.

Actually, I have the same issue. It's the really sensitive edge scroll, isn't it? Yeah... its really annoying when your trying to take a picture or something like that, but you get used to actually playing like that.

Most mice these days have adjustment software that lets you set mouse sensitivity on a per-application basis, so you could try fiddling with that

I have edge scrolling turned off because I'm playing in window mode. I hold down the right mouse button to move across the neighborhood. That's pretty slow, you might try that instead.
