With what exact MacBook Air and which Mac OS X version do you experience such behaviour in what applications?
How do you scroll (trackpad, mouse scroll wheel)?
How do you scroll (trackpad, mouse scroll wheel)?
Does it happen in all applications or just one or a few?
Does the same occur in another, even temporarily created, user account?
